I’ve mentioned del.icio.us a number of times on this blog. It’s really one of those services that you have to “get” in order to really appreciate. I haven’t done a great job of describing it here, but I’ve found some pretty good explanations tonight. First, one of the VC’s investing in del.icio.us describes why he did it. In his post, he links to a good screencast by Jon Udell. In it, you can watch how he uses del.icio.us (which is pretty much how I use it, too).
