There are some services you can do for some of the big one's like Twitter and FaceBook. I don't know of any, though, that can send to places like geeks.com.
Still, though, there are a lot of apps that can send to most of the social networks you'll want to post to. My favorite is hootsuite.com.
With a free account you can post to Twitter, FaceBook, a FaceBook Page, LinkedIn, Ping.fm, WordPress, MySpace, Foursquare, and Mixi.
I use Hootsuite but to be honest, all my social profiles and any website I belong to is linked to my Twitter. Therefore, Twitter is the ONLY thing I ever have to update. It makes life a lot easier. I set my former boss' social networks up like that as well. You never even have to visit those sites.
Simply, embed a widget on a site with your twitter info or use rss and add it to your feed. I know you can do this for Facebook, LinkedIn, and many, many more!
