Update, June 13, 2007: After playing around with the site a bit more, I discovered that you can add more than three social networking sites into your profile.
In last week’s Friday Five I pointed to a TechCrunch review of MyLifeBrand, a social networking utility (and yet another social network, in and of itself) that lets users aggregate social networking memberships and navigate between them from a single place. I was intrigued, so I applied for membership in MyLifeBrand Alpha and to my surprise was immediately accepted.
So far, all I’ve done with the site is create the space where I can access my top three four social networks (Facebook, MyRagan, and LinkedIn and MySpace). This could be a good solution for anyone managing multiple social networks. The Alpha version only allows you to place up to three several social networks on a page, and you have to go to the “snapshot” view to input and view them.

I was going to post about this because I had the same experience, so you beat me to it! I did find it to be a little bit clunky, but it’s still in alpha so I can’t really knock it. I think it’s a good first step in the aggregation of social networking tools … which I think will be very necessary as they become more pervasive.
Charlie – I poked around a bit more on the site and discovered one can add more than three sites, so I added No. 4 (MySpace) just to test it. It seems to work.
Sounds very interesting, I’m going to sign up and see how it works!
