I hope you stick around, but don't blame you if you don't. I was a long time lurker/reader that rarely posted, but have lately been making an effort to post more. I share the same frustration as you, a lot of discussions devolve into the same negativity and talking points no matter how they started out. It also seems like a "good ol' boys club" where the same handful or two super posters dominate the conversation, mostly only replying to each other's posts with nitpicking. But, I'm sure most message boards operate this way.
Overall, I'd love for this page to be more welcoming to new folks with different ideas/perspectives.
