I just got an invite for Dock.io ... and said, wth, yet another social media? but it appears this one is meant to share info with all of them.
Not sure how I feel about that either. I may sign up just to see what's what. I don't necessarily want facebook and twitter and linkedin to share data. Separation of personal vs private. My linkedIn is professional, facebook and twitter not so much.

Anyone actually use it?
