SO is insane to me. I tried to contribute but I believe it was my third post where someone edited my answer "to tidy it up", wherein they charged the code in a manner that it no longer solved the problem, resulting in the answer getting criticized and voted down by others claiming it doesn't work. I couldn't believe the audacity of someone to just edit another person's post and not put huge warnings up saying "Edit: Modified by ____, not retested, original code here: ___". Then I found out later that this is just common practice on SO. What a mess of a site.
