Thanks Crum,
I have a facebook page ready, but not thatmany FB friends ;-(
I'll try the sites you mentioned and look for a few more, at the moment i sent requests to appalicious/androidTapp/bestandroidapps/etc

My app is a game, so it doesn't really solve anybody's problems, apart perhaps brain numbness hehe
I want to stay away from paid adverts at the moment, i have a friend who had a bad experience with that
