Problem I have is that there is no way of knowing why posts are down-voted. Quality? Politics? Just wrong? No idea. Sometime I see posts which are factually correct, but clearly unpopular and voted down. And to be utterly fair, I'm not even sure why I've down-voted or flagged in the past. Cant even remember if I've flagged.

Now Im actually thinking about it, I think I'll only up-vote in the future, and I think that would be if I think I've learned something from a top notch post. Anything else feels like some sort of censorship, vanity or whatever.
