I signed up with del.icio.us, the "social bookmarking" service, a few weeks ago (found via Liz Lawley, who's had quite a bit to say about it). So far I'm not really using the social aspects of it, but it is a handy repository for links I suspect I am going to want to look at again, but which I don't want in my bookmarks or which I'll need from another computer. Lately, del.icio.us/donutage has been especially useful for holding links for my off-campus course (hence the links to Kentucky curriculum standards).

One thing I did find through del.icio.us: the iTunes Music Store has a customizable RSS feed generator, which allows users to watch selected genres for new releases and recently added songs. Neato!
