A programming Q&A site, where users get upvotes for good questions, answers and comments, and also get downvotes for bad answers, questions and comments. The votes determine your rep (the highest I've seen there is 300k Skeet
Skeet)
The users
don't play around better not fuck with them. And
don't post silly questions, answers, and comments except your Jon
Skeet (He has a lifetime supply of upvotes, if you downvote him your wasting your time) . Can be a horror to new users though. Plus its perfectly designed.
Bob :
Dude, I totally asked an
innocent question on stackoverflow and got 30 downvotes in the first 10 seconds.
Me : What did you ask?
Bob : How to print a line to console in
java.
Me : Ahahahaha I got 100 downvotes when I introduced myself with a question.
