As far as the wikipedia of bad comics, I try not to read stuff written by stuck up assholes with nothing better to do but write hate. Someone who has time to read through whole comic for the sake of writing hatred is no one with a viable opinion to me
they're just internet bullies. So I don't have anything to say about the wikipedia thing beyond that.
As far as the questions of independence from Dave, it's just not possible : ( It's still his site. If you want a different site, either make one or find another one. Take it from someone who has had to move around a lot. Websites and communities are a top down kinda thing. Once Dave stops caring, the community follows through. Dave needs to give the site up to someone else, which just from knowing website owners, it ain't gonna happen.
I've tried so hard to change a website myself. I used to be an admin on a roleplay site, and I saw direct reaction from my actions. Once I took my gloves off, so did everyone else, and got so bad it became to site's undoing. If there was ever any fire on SNAFU, I suppose the bright side would be that the site endured it and is still alive today, even if it seems like a smolder.
