Del.icio.us is a website that allows you to bookmark your favorite websites. You can then check to see what other people have bookmarked your favorite sites. It's sort of a network of websites. I have, for example, bookmarked ecrl.lib.mn.us as a website. Four other people have also bookmarked this site, including "bmisselt" (ECRL Director). By clicking on her name, I can see what other sites she has bookmarked. Her first five sites are SirsiDynix, Kananbec County Times, Internet frog.com, Chippewa Herald and Star Tribune. I only have four websites on my bookmark.
I haven't found a use yet for tagging--maybe it is like a shorthand way of finding a site if I have numerous. With four, I can keep track of where they are without a tag. I am tagging these blog postings though, for whoever evaluates them. I'm tagging each with their Thing number. Well, one more website with a log in. One more thing to occasionally check. It will be interesting to see which ones I keep up with.
I did finally get to do some IM the other day. A teenage girl said that she would be my Yahoo instant messenger friend. I was able to "message" with Leah so I consider that I have at least tried this type of communication. It was fun, but unless I can IM with someone about library business, I am probably wasting my time.
