I'm splitting myself in two on Facebook.My profile page is "me", to share and be shared with my friends. Stuff related to technology, social media, and in general things that might play better in the world of work, will be on my page, "Steven D. Stern" and on twitter @sds52.

I've put a live widget in the left sidebar of the home page that displays both my Klout score and my PeerIndex.
For those interested, here's the code for the block:
