Poison, if that's all you see, you're missing a LOT. Sure, there are some personality conflicts here - it's a community of extremely independent personalities, it happens, ya know? I think most of us really are here to help each other, offering knowledge, ideas, experience, or even a laugh - whatever we have to contribute. In turn, we feel free to ask for the same from the other members - that's how it works. It would be better if we could confine the criticism to private msgs, but the Moderators do a very good job of keeping it civil, nonetheless.
I've seen some websites that are almost entirely positive affirmation oriented, and personally, I lose interest in that pretty quickly. As somebody wise once said "When two people agree on everything, all the time, one of them is lying"
