Just came across a new player in the social media game...
sez.us
Currently in beta but taking registrations. Took a brief look and it's a VERY basic format with very few features (if any) so it's not going to out do CoSo anytime soon (even in ostrich mode).
Got no idea who's funding it either.

@TheLegend_AZ Look up Joe Trippi - he's the founder. Sr advisor on the Lincoln Project among other things, talking head at CNN, etc
@kismatt I know who he is.
