There's definitely a "silent majority" (and not always that silent) of good people here. If you stick to the technical posts especially, there's a good crowd.

I got most of my karma before my account was "moderated", which is California Passive Aggressive for having your posts downplaced into obscurity (also called "rankban" by some) and guaranteeing that you never have the top post, no matter how many upvotes you get (and you won't get many, often, given that your posts are insta-buried). I also deal with a slowban (5-second load times when logged in) and will often get 4-5 downvotes within minutes of each other, for which I don't know who to blame, but it's annoying.

I've kept posting out of a sense of resistance more than anything else. I refuse to be run off the board. The passive-aggressive "moderation" to my account actually backfired and kept me on the board, even as my increasingly justified sense of indignation grew.
