It's a circlejerk for some part that's for sure. But not for the most part. I facepalm at the circlejerking that goes on but it by no means dominates this board.
actually, it kinda does. I see so many people who post comments, and get much more "i may disagree with what you have to say...." responses if the first poster was a well known and liked person.
Same goes with how projects from some users get tons of posts and comments, while other just as good ones dont.
I mean im sure if anyone responds to this i'll get a much more "**** you" type post because of me not being a well liked poster.
The circlejerk aspect of any established social environment is always prevalent. The internet, despite being more about anonymity, is still the same.
