PS to the above... I hadn't seen tedster's link or Matt's video at the time I posted. My comments address more the rate of link growth... which is how Google might detect gaming the system under this social media scenario... rather than just the quantity. What underlies Google's philosophy of course relates to both.
Again, build good content for the long run. That produces the kinds of links that Google likes.
