Let me say that I have only yesterday signed up to reddit, for the first time, under my own name. And that I would happily go elsewhere for intelligent feedback. But if I was wronged by a bigger adversary (government, business, etc.) Reddit would be the first place to air my grievance.

People post pictures of their kids, their pets, their hand-drawings, hobbies, even their own private parts (if you know where to look.) I think Reddit covers the whole spectrum of the human experience .. if all humans were charitable, fairly well educated, suburbanite, closet-Marxists with short attention span (which I emphatically identify with :-)
