Hi John, I use Diigo as a kind of information-management tool, and I see it's great novelty in keeping the connection between the information and its source. It's indeed the only tool available that lets me interact with the source itself - highlight text, add my notes on specific highlights, comment on the whole page, tag it for later, and share it with others. I also like it's search and viewing capabilities. About the social aspect - I notice that some people, while not great writers themselves, are very good in picking out the highlights from any given text and tagging it. You can easily notice that at delicious, digg and clipmarks. On a wider perspective, imagine that top thinkers, scientists and other inspirational people start to use Diigo, and share some of their I know I for one would like to follow what Noam Chomski and Kevin Kelly are reading and finding worthy.

CityWall is a large multi-touch display installed in a central location in Helsinki which acts as a collaborative and playful interface for the everchanging media landscape of the city. The new interface launched in October 2008 also allows working with 3D objects, which enables multiple content and multiple timelines.

CityWall presents images, videos, descriptions and discussions on how nature in Helsinki benefits and disturbs dwellers. A single tree, for instance, can be both a useful physical shelter, an appreciated element in the urban landscape, a source for an irritating pollinosis and a danger for traffic. Many of the changes in the benefits and nuisances of nature are, at least partly, dependent on human activities. The settling of rabbits as permanent residents to Helsinki, for instance, follows partly from global warming that allows released pet rabbits to survive winters in urban green areas. To participate in this discussion, visit CityWall Flickr page and add comments there. You can add images to this discussion by attaching tags "cwnicehki" for nice things and "cwnuishki" for things that are nuisance in Flickr (additionally put tag "cwhkirabbits" if the photo includes rabbits!). You will need to establish your own Flickr account for this (this is a free service).

Many free RSS services let you subscribe to oodles of news sources that so you don't have to hopscotch from site to site to get the scoop. But the $29 FeedDemon 2 is the best RSS reader for steamrolling through thousands of feeds. Need headlines from the science section of the world's major newspapers? Check. Want the latest research from insider blogs about solar power? Check. FeedDemon is faster and more customizable than browser-based freebies, and it also lets you access feeds online.

2. Wikipedia You might shun this online, open-source encyclopedia if you've ever been burned by prank entries or fudged facts. But because anyone can edit Wikipedia, it's a richer resource than Britannica for subjects off the beaten path, such as the > 1960s underground press > or > rivethead subculture > . Though it's not the only source you should reference in term papers, at least Wikipedia gets you started. >

But most important for me is the large volume of very interesting news that will not become "news." This is the kind of material that is more interesting than random pages but which lacks an appealing hook to place it on the front page of a magazine or even a news website. Often these items are timeless; they don't make the front page because they could be run at any time. But they are more valuable than odd curiosities. Because of the voting, tagging, bookmarking process enough people find the item worthwhile that they rise to notice.

I have encountered no other process in the world that is better at surfacing "news that stays news" and "news that will be news" better than these collaborative filtering sites.

Some of them provide a ranking of most popularly bookmark pages of the moment. I use this ranking function without bothering with the tagging part of sites.
