I've been operating on wikipedia since 2002. Small edits here and there, I only created an account when I felt the need to add pictures.
During the last year I've noticed the alarming increase of a type of user that makes people swear never to use wikipedia again: the rulebook banger. I don't mean a rule nazi that sticks by the rules no matter what. I mean a person who will make it his personal quest to beat you and your edits into the ground because he has some sort of unfulfilled desire in real life. He literally knows all the rules of wikipedia by heart and will use them to enforce his point and his view only disregarding them or brutally enforcing them when it suits his needs. He will say your sources are not valid, remove your images and revert your edits just because it makes him feel important.
This my friends is the rulebook banger and he is the main reason people quit wikipedia.
You probably know that Wikipedia's best articles become Featured Articles. But did you know that a similar process exists for images? Go to Featured Picture Candidates to help judge which images are both attractive and valuable to Wikipedia.
Of course, the best can be found on featured pictures. Many of these photos are taken by Wikipedians. If you are a photographer, you can add yourself to the list, or encourage others by nominating great photos you come across. Feel free to use featured pictures in your own works (according to the terms on the image description page).
This user feels that out of processdeletions subject to an administrator's whims rather than consensus damage Wikipedia more than any userbox ever could.*
