A blog post looking at the ways people use delicious and highlighting that just as much of the stuff on delicious is junk as the reset of web.

It takes a little getting used to, but Delicious is an incredible tool for keeping track of websites and finding other ones. I never really bookmarked things before delicious, but after a little practice, I can't imagine life without it. I have feeds for my favorite tags (like one for GIS) so I can see what's happening in the web world. Because of the interests of the people using it, it still tends to be pretty techy in the links in there, but more and more people are using it all the time, with their own interests. It's worth trying to get to know it, I think.
