Thing 13: Huh?

Del.icio.us. Not really getting it. I'm not much of a bookmarker to begin with, and this site is really lost on me. I don't see Del.icio.us as a great research tool, but I guess if you want to save your bookmarks online, well, here's the place to do it. I also don't get the whole "See what other people are bookmarking" and "connect to others" come-ons. My question is this: are people really "connecting" on sites like this, or is it just curiosity and voyeurism?
