Wikipedian Zombie 

Someone who keeps clicking the "Random article" button on wikipedia in the hope of finding something vaguely funny or interesting.

The first 10 times he clicked random article he could still communicate, but now he doesn't respond to any sort of stimulation. It's no use, he's a Wikipedian Zombie now.

Wikipedia Vandalism 

Wikipedia vandalism is an act of course where the user will add an irrelevant comment, remove all the text, replacing the text, adding links etc, which have nothing to do with the original article.

Person 1: Why the fuck are there Mario links on the fucking Sonic page on Wikipedia?

Person 2: Some faggot did Wikipedia Vandalism again.

Urban Wikipedia 

n. A hypothetical future version of Urban Dictionary in which it is innundated by entries that are not so much definitions of words as they are extended, elborate, and baffling encyclopedia-style entries on pointless minutae (see wikipedia).

"Entries on characters from Stargate SG1? When did this turn into Urban Wikipedia?"

"Who the fuck keeps submitting these tracklistings of The Who albums? This is Urban Dictionary, not Urban Wikipedia."

The Wikipedia Effect 

The Wikipedia Effect is the tendancy for inquisitive people to become caught in an endless series of pages on the popular open-encyclopedia, "Wikipedia", to which they are forced to read every single page they've opened.

This tends to happen thanks to Wikipedia's inter-linking model, which links important words in a particular article, to an entire article on that word. The trend can then easily cascade from there, ending in dozens of pages that a user finds interesting.

"Don't you just love The Wikipedia Effect? It sure is a good way to stave off boredom."
