A Web 2.0 (social software) directory
Go2Web20 is handy (although it isn't complete). You can click on Select Tag and up comes a list of keywords. I then clicked on 'Animation' and found a clutch of free online tools. Ditto 'Voice'. Their drip feed of new tools is of course on Twitter. For Web 2.0 selection criteria in education, see the bottom of this post on TekTrek.
(I'm still unsure whether people know what is meant by the obscure term 'Web 2.0' - which I tend to refer to as 'social software' although that's not quite right either. The old web was basically a case of established media and technical authors producing stuff and the rest of us looking at it. On the new web - Web 2.0 - increasing numbers of us create, upload, author and interact. We Twitter, Flickr, YouTube, Skype, blog in the medium of text, video or audio, share bookmarks, reviews and ratings, produce timelines and 'mashups', negotiate encyclopaedia entries, and 'lifestream' on Facebook and Twitter. I don't think it's an exaggeration to say that Web 2.0 represents the biggest democratisation of communication and culture in the history of humankind. But we'll see what happens when the power runs out.)
