Not that any still uses Delicious, but I actually have an account where I bookmark interesting things I find on the interwebs. It was easy to set up and, with the Firefox pluggin, I can bookmark on the fly. Back when I changed over my WordPress theme to a basic look, I added some special features to the home page at www.houseofcarr.com. There you can not only see my latest posts, but you can see my latest status updates (via Twitter/Facebook) and my Flickr accoount. Since it had a pluggin for Delicious, I signed up for the service. This way, I don't have to write an entire blog post with hyperlinks to interesting articles.
So if you're interested in what I find interesting: first, get a life. Second, you can track my Delicious Bookmarks.
