I don’t think that social media is stalling. I think people become overwhelmed and a little burned out with overload.

I had meant more that SM’s growth was stalling then that the entire concept was rubish.  The interesting part is that investment continues as if some of these giants aren’t having any trouble at all.  I hate to bring that bubble word back up, but it sure smells like it.  Foursquare may be the latest company that can’t reach its previous valuation.
