One of the two discussions that lead me to give up on Diigo. This is the point at which I give up on social bookmarking sites, in general, in part because of the reasons I mention in this discussion. No mas.

If you entered my pages from one of the rings to which the Ravine belongs, you should see the links for your ring below. If you don't, either because Webring has been merging rings again, or because you entered my pages somewhere other than on the Ravine, just go to the ring return page for the Ravine on 20m.com or Webng, and we'll sort this out. If that page is down, you can try my global ring return page

"The Ravine" is the name I've attached to the space associated with this account on mine on Diigo, and associated page take you to the two copies of the main page for that distributed site, which are located at http://josephdunphy.20m.com http://joedunphy.webng.com

If you'd like to be automatically notified when more content is available for you to read on my bloggish group of one, you can can that set up for yourself by visiting this page on the homepage for my Diigo account.

Somewhere to follow my Diigo bookmarks, when they aren't available on Diigo.

General information about my pages on Diigo, and pages connected with them, elsewhere.

How to get that, even if we aren't friends on Diigo.

Mirroring the content on my bloglike Diigo homegroup, just in case said group should be offline.

Writing about some of the livejournals I've visited while writing my pages on Diigo. (philosophy, scientific skepticism and other subjects)

If you came to my pages at Diigo from a webring and wish to return to it, now, you should find the code you need on this page. Be sure to click onto the url you see above the preview window, after clicking on the link, to get to the ring return page instead of the preview page. Yes, I know that's a little confusing, but that's Diigo's doing and there's not much I could do about that, other than maybe look for a new hosting service. Again.

Connecting to discussion related content, roughly the same subject matter which you'll be seeing on my Diigo pages, but on a different social networking site.

I spend a little time talking about what I intend to do with my profile, here on Diigo, and then provide a few links and pictures.

I have difficulty taking this one seriously, which might not be an utter surprise, given the fact that we're talking about a post about an alleged research project posted to a science fiction site. An unnamed "researcher" (identified elsewhere as Mark Holley of Northwestern Michigan College) claims to have found a Stonehenge like arrangement of boulders at the bottom of Lake Michigan. Looking at the picture included in the article, the only thing circular in it seems to be the field of view.

A thumbnail of what is said to be a sonar image of this supposed find can be seen below. How would you describe the distribution of the rocks you see in this image - as being a circular arrangement, or as something more linear, with a little random scattering - as one would expect to see if the river of ice that carved out the canyon that became Lake Michigan had melted, and dropped the rocks?

















How would a stone circle - were one present - end up at the bottom of a Lake that every child growing up near its shores knows was carved by glaciers? The article states "These submerged stones could have been raised by local populations at a time when part of the lake bed was dry, in the late Ice Age." Except that the Lake, again as we all grow up knowing, was initially filled with the water from the glacial melt, so there was no such time - the Lake has been retreating, not advancing, over the millenia.

Another user (lprnal) tries to make the blog writer's suggestion sound more reasonable than it is, saying "lake michigan has been shifting and evolving for quite a while now, and sometimes it's not slow at all. For example in the door peninsula, there are bluffs which are quite high you can stand on, that used to be right on the edge of the water.", but again, this is not due to the ground around the lake moving, but to the level of the lake dropping.

So I found this all quite strange.

Note: Those who wish to read the article itself, which I've bookmarked, should follow this link:

and continue from there. Ma.gnolia, where the Ravine was original set up a few days before the fun of January 30, 2009 (ahem! cough!) doesn't (didn't?) allow us to edit links in discussion group posts after the fact, so I'll be making lavish use of offsite redirect pages over there to allow me to update links as needed. Maybe.

Assuming that Ma.gnolia ever manages to get back online. As for here, I'm still learning how the Diigo system works, so I don't know what's needed on this site. That I can embed photos in the text, instead of referring the visitor to images elsewhere as one must at Ma.gnolia, and use some html, comes as a pleasant surprise.

If you'd like to be notified of updates to my bloglike (blogish?) homegroup on Diigo, and you have a Yahoo account, you should join this community. Just sign into Mybloglog with your Yahoo account, if you haven't set up a Mybloglog account already, and you should be ready to run in about a minute. Just remember to click on "my home" and look at your own page before trying to set your nickname in IE, because of a small bug in the system.

I just edited an old post on a group, and noticed that Diigo has jumped onto the bandwagon and started adding rel=nofollow to all outbound links in its groups. Guys, please stop doing that.

The standard argument for using nofollow is that its use deters spammers, even if the rate of spammage would seem to have increased since the introduction of nofollow. This belief can easily be seen to be nonsense by anybody who has ever waited for one of his sites to appear in the search engines listings. Why? Because that process can take months, sometimes even years, and spam sites don't tend to live that long. Within weeks of a site being so promoted, sometimes even within days, complaints about the spam will have gone in to the service hosting the site and to the site's registrar by the truckload, and the site will be gone. Only to be replaced by a brand new site at a brand new location, selling the same old stuff, as anybody who, out of perverse curiosity, has ever clicked on a link on a semi-old spam message (and then checked his newer e-mail) almost certainly has seen for himself.

Spammers work by getting large numbers of visitors to go to throwaway sites that won't live long enough to rise in the search engine ratings, so pagerank won't matter to them. Logically, it shouldn't, and if we take a look at spammer behavior following the introduction of nofollow, we find no evidence whatsoever that it does. It can, however, matter immensely to those who are trying to establish a web presence for themselves honestly, by doing exactly what they're supposed to be doing, that which the search engines are supposed to be encouraging them to do - by creating and posting content that people want to read and link to. Let's say that one of us posts content to a "black hole", a site that (like Diigo) has rel-nofollowed all outbound links, including the homepage links on our profiles. (Check it out - Diigo has done this). Let us say that somebody looks at the content, likes the content, and links to it. Diigo gets a search engine boost, but the person who took the time and did the work to create that content doesn't. Meaning that his other sites would have done better in the search engines if he had posted that content elsewhere, where nofollow wasn't being used.

In effect, he is being penalised for having chosen Diigo (or some other black hole) as the place where he would post his content. Nofollow hurts the legitimate poster, while having absolutely no direct impact on the spammer. But it can have an indirect impact, as one can see by looking at services like Simpy, where the spam has taken over.

Think of the difference between being the one guy who's speeding while everybody else is staying below the limit, and being that same guy when everybody else is doing 85, too. You're still breaking the rules, and you still know that (theoretically) you can be slapped down for that, but there's a great feeling of safety in numbers. As the ratio of spam to legitimate content goes up, the spammers get bolder and more aggressive, as anybody who has ever been away from a forum he moderated for a little too long knows - spam tends to snowball, and probably for the same reason that the number of speeders will start to soar after a point; because one's chances of being one of the people grabbed and sanctioned are dropping. The life expectancy of one's spam is rising, and the profitability of it is doing likewise in the process, a thought that will lure more spammers in to take advantage of this opportunity.

There's the indirect impact on the spammers - by undercutting the incentive given to one's legitimate contributors, one helps create a friendlier environment for those spammers, which perhaps is why the rate of spammage has gone up since the introduction of nofollow. The law of unintended consequences has kicked in with a vengeance, and why wouldn't it? If somebody, in "real life" (offline) decides to treat all of his visitors as if they were scofflaws, hardly anybody is surprised when he eventually finds himself surrounded by nothing but scofflaws; honest men expect to be treated with respect. Why should life work any differently online? Because treating us all like we're spammers, even after we've proved that we're not through months or years of honest posting, isn't even remotely respectful. Even if it is fashionable.

Yes, I know that dealing with spammers can be exhausting, and I'm sure that one will be greatly tempted to believe that a shortcut can be found to doing that tedious, emotionally unrewarding task, much the same way as some of us would like to believe that we can find a fun way of getting around the need to do cleanup in the lab, or that's there's some diet that allows one to lose weight and reduce one's cholesterol while eating all of the steak, bacon and chocolate one wants, maybe by nibbling a few acai berries or something like that. But reality is what it is, and it either gets dealt with on its own terms, or it gets worse. Sometimes, a lot worse.

One doesn't win popularity points by reminding people of this, but it is the truth.

Proper credit - where I found a few of the photo pages I've submitted to Ma.gnolia in the past, and now am about to mirror on Simpy and Diigo, as I wonder whether Ma.gnolia will ever come back. (I'm writing this on Feb.4, 2009; Ma.gnolia went down on Jan.30). When you see me refer to "Anatoly", this is the Stumbleupon blog of the Anatoly of whom I speak.
