I have to say, I often do get quite surprised when I read the forums.
By reading it, it gives me the impression that 90% of the community are just dickheads.

My experience since Beta has been the complete opposite.
Since I started, I've run into a grand total of 5 people who fit into the categories that I read here. The rest have been extremely polite and willing to help me out when I tell them I'm new to something.

I'm not saying that there aren't a lot of bad eggs out there, just surprised to hear, considering I haven't seen many.
