It seems to me that they would be better off paying people cash incentives per facebook or twitter post, or per friend brought over, rather than handing each other steam power by posting total junk that degrades the platform. I for one was totally for this thing to work, but now, seeing how it actually works in practice, I'm quite disillusioned. If many new users feel like me, they are going to lose millions of people. For now, because I like the idea so much, I will give it a further chance, but I'm going to hold off on making strong contributions until I see whether there is a point or not. And that depends on whether this a a scheme or a social network/content site. So far, I only see the former. Which means that anything I post is just as well wasted posting on facebook as here. More so, because facebook will be around in a year's time.
