Twitter tools and Diigo buys Furl
Smashing Magazine has a list of "99 essential Twitter tools and applications." Definitely worth bookmarking for looking at now and later.
Discovered it through Diigo -- the social bookmarking service has taken over Furl.net. While Diigo and Furl say that importing Furl's bookmarks is as simple as one click, I've not gotten any of the Furl material in my Diigo queue yet.
I'd suggest that if you have a Furl account you sign on and download a zip archive.
