Nah man that's not true. This is a wonderful place, I joined yesterday and I now have like, 10 awesome friends.
Just find a topic to talk about really, or impress them. Most of the people here sometimes don't reply because they got nothing to say, not because they hate you. Just be social. If they still don't reply to you, they don't worry, it's not the end of the world, it's their fault for not having a nice person like you as a friend or maybe they're really just shy.
Also I totally disagree about "don't care about people here just post" that's not true, if you just post then there's really no reason to stay.
