I caught AC fever soon after getting my Razr Maxx in 3/2012, and found out how nice it feels to help others out in these forums.  I started contributing so much that the folks behind this whole thing asked me to be an Ambassador, which was a real honor, and I've continued to enjoy the sense of community and the problem-solving that comes with the position.
I'd say the main thing that was clear when I first started looking at various Android forums was that on AC, people were generally much nicer and less trollish, which I think is due in very large part to the great job the Moderators do in keeping the discussions civil and on topic.
