Well I've been there for more than a year but there is a very Low traffic, many people looking for free things and I didn't make any dollar to this date. You need to do so much self promotion and already have a large fan base before trying to use it
Ok so PocketStars just launched and for some reason it's the first site i got so excited about.
I gave 5 reviews for everything as it's too early to comment on other than the support. They are great at that so far.
