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.
Many article titles are disambiguated with parenthetic qualifiers, like this: [[Self (psychology)]]. But when you want to include such a link in the body of an article, this would look rather awkward. So all you have to do is use the "pipe trick", like this: [[Self (psychology)|]]. Notice the "|" character stuck in there at the end of the link? That makes the link look like this: Self, without having to type the name of the link after the pipe!
This trick also works with namespaces, so that [[Wikipedia:Tip of the day|]] (again notice the pipe character) displays like this: Tip of the day.
This user feels that out of processdeletions subject to an administrator's whims rather than consensus damage Wikipedia more than any userbox ever could.*
