Why do so many crazy people use Post Almost Anything?

Why is it that the Post Almost Anything user base appears full of crazy people? Just one glance at the Rants and Raves section reveals the work of pissed off people that can't spell or just don't take the time to proof read their work. Their work is often full of wild accusations include poorly edited pictures of those that displease them. As an neutral third party I am often not in a position to judge the veracity of their statements, but I also know the signs of a disorganized crazy thinker when I see them.

I will be browsing this site from time to time looking for the work of crazy users and calling it out.
