This link gives information on the difference between a directory and a folder. The reason I found this link so useful was because it outlines the difference between the two for Mac and PC users.
Congratulations, Gordon, on being the very first to post! :)
I will say I'm not very impressed with the link, though -- it's a bit fuzzy on whether there is or is not a difference between a directory and a folder, except in a technical sense on Windows Vista. (I'd argue that in general there isn't, though I grant you there are special cases.) And you can't tell who wrote that piece, and it comes from the support database of a particular software company rather than from a site that's dedicated to explanations / teaching / learning / education. At least Wikipedia is deliberately trying to educate people, and it's better on this issue, I'd say, and provides a clearer argument that a directory is something structural in an OS whereas a folder is a visual "metaphor" for a collection of files, which may or may not be an actual directory: http://en.wikipedia.org/wiki/Directory_(computing)#Folder_metaphor
In addition to the content management systems we talked about today like wordpress, there are plenty of other great content management systems out there for people to use.
Although that article was written way back in 2009, I'd say it's still pretty accurate. All the CMSes I know of are in that list, plus some I hadn't heard of.
I came across this as I was looking for history of search engines and its pretty crazy that the site Topsy has been able to save every single tweet since twitter launched! that's 300 billion tweets!!! and you can search them all as it is open to the public. I hadn't heard about Topsy but it seems like they are gaining a good reputation and going against big search engines like Yahoo and Bing.
That's useful, Milan, thanks. Note, though that it's not super-clear what "get" means in this context -- I'm sure a lot of people, like me, get their news from several of these sources. I get news from radio, the Web (including newspaper websites and Google News), and social media, and I'm not sure which of those sources is primary.
