CiteULike

Increasingly people are turning to web-based services to manage their personal information clouds. Here's mine:

Photos (and chat!) Flickr
Blogs : Bloglines
Bookmarks : Del.icio.us
Did I also mention Furl - haven't tried it but it behaves a lot like del.icio.us, but with storage of bookmarked pages and more privacy. Note that this is more of a commercial outfit than open-sourcey del.icio.us - look around as user:demo password:demo to get a feel if that gives you goosebumps.

The deal about these is that they don't care where you are, and they encourage sharing.

And now, real work. Academic citations can now be gathered in the same type of thing. Throw away your clapped out old EndNote and RefManager, embrace the shiney new world of CiteULike,. online, sharable, taggable reference collector.

Note the big big thing in common: tags tags tags tags tags.
