This is usually done at the expense of other social activates like asking girls out, or talking to friends. And the seasoned wikipedian can often be seen fapping furiously after writing an article he considers to be particularly accurate.
Kearney: I'm a wikipedian, I recently corrected some glaring inaccuracies on the Captain Picard page!
Jenny: …okaaay *turns around*
Any changes to an article with which the Wikipedians disagree will throw them into confusion and panic, and it will be debated endlessly by them in their attempts to dissect and scrutinize every minutiae of human existence, no matter how worthless or trivial. This further strengthens their delusion that Wikipedia is an actual encyclopedia with any educational worth rather than a glorified video-gaming rumour mill.
Unless you are one of them, in which case you should probably get back to Wikipedia to write an article listing anime characters with "z" in their names or whatever the hell it is you people like to do.
