A tad early on buy outs. If social interaction with Mobio continues to grow and is continously growing its' userbase and celebrities, then yes, it could be a take-out candidate.
But right now, I doubt any companies are looking at Mobio seriously.Too early, not enough statistics, and not a real threat at the moment.
On a side note, that Mark guy on Mobio puts a heck of a lot of time into those pictures.
