I discovered DandyId recently while playing around with WordPress. It’s a tool that allows you to enter in the links to many of your other social networking profiles.
I’m currently working on a book on social networking, so the number of accounts that I have has reached ridiculous proportions. I’ve seen a couple of other sites that try to tie things in together, but DandyId is the most comprehensive one I’ve seen so far.
One small hitch: its still missing about a dozen of the sites that I have accounts on.
