We don’t do any paid advertising currently. We have some ideas that we will be implementing soon, though, that will be geared towards bringing more gamers in. A Game API (for high scores, trophies and save state) is one of them. It’s been in development for a while, but should be ready to release fairly soon. Also, we’ll be redesigning the front page of the site with some new features that should help to get some more games noticed.
I’m going to definitely test out using a bayesian rating system. One of the current problems of the site isn’t that new games pop up in the top rated, but that the top rated doesn’t change at all and it’s hard to get rated higher than the tops. Adventure games seem to be dominating the current highest rated. We have some ideas to combat this, though, to show a wider variety of good games.
Sending money from one PayPal account to another is free. Been sending money with no problems so far. Where did you see the $0.33 per transaction?
Thanks! It’s definitely growing and pretty exciting.
