Delicious.

I must admit, other than using delicious as a way to find things, I'm not really getting this one. The social aspect of it is sort of eluding me. Perhaps because I dont' really care how many other people are looking at something, or whether they like the same thing I've enjoyed? I did find lots of fun stuff under a few headings and set up my own set of tags for them, but I can't see using them for anything beyond portable bookmarks, really.

This is a bit of a lame entry, but really, this particular application isn't ringing my bell.
