You may remember me stating in the past that I have an aversion to e-mail signatures. Well, I found something that is the sure-fire cure to those overly long e-mail sigs.
And that’s Krunchd (pronounced as it looks, "crunched").
I created a Krunchd page http://krunchd.com/menga. I included the all the social networks I participate in, my web site and so on. It was stupidly easy to do and only took a few minutes to set up.
Once you have your Krunchd URL you’ll receive an e-mail where you can add/remove/modify anything on your Krunchd page. So if you happen to join up with a new social network or have other blogs you author, etc., this can come in really handy.
Krunchd is especially handy as an e-mail address signature. As you know, you can’t modify e-mails you’ve already sent. Once you’ve sent them, that’s the way they are for life. But with a Krunchd link in the signature, any time someone clicks on it, your most up-to-date information is present.
Very cool, very easy, very useful.

Rich, I like Retaggr for this sort of thing, you also get a widget that you can use on your blog or web page. http://www.retaggr.com
