Started by one of the chodes who brought us Blogspot, Metafilter is one of the web's worst corners of SJW neurosis and paranoid political correctness run amuck. It started out as a not-bad group blog, and eventually became a very, very twisted little community.
Insecurity reigns at MetaFilter. The moderators will kill a posting for any or no reason. The heaviest users suck up to the moderators like vacuum cleaners on a tit-nipple. Back-stabbery is a daily occurrence. The "database" is full of lame trivial bullshit. Anyone they dislike or is seen criticizing them, even on another website, is instantly banned. And the best part: their community is dying, and they refuse to discuss or even admit it.
