hi man, thx for the reply.

I am giving away 1 block / user for free. for now. so, you are right: the same success is def. not replicable. I do not care about making money (or a mill. bucks) with that site, I only care about having great projects featured on the site, and then, get traffic. If that works out, I may sell a few blocks. Later, I might introduce a re-sale feature as well.
