What is Wikipedia for? It's for bots.
This machine kills trolls: How Wikipedia’s robots and cyborgs snuff out vandalism writes up the work of the Wikipedia contributors who have written robots (bots) that automatically extirpate contributions to the encyclopedia that are unwanted.
Alas, the result of all of this highly efficient robot-driven editing is that many new editors first interaction with the system is not with a human being, but with a faceless robot. The real worry is that the crowd of new editors that used to flock to the site to provide modest and well-intentioned edits are being systematically pushed away by the overroboticism of the systems administration.
Bot vs bot is a long term war that has no human winners, and the quality of the resulting system is poorer because the bots feed largely on newbies. Only when you master the gauntlet of robot overlords do you eventually get welcomed into the inner sanctum of humanity. Those who stay will be always watched over by the machines, and only a few in the Wikipedia elite will master the necessary skills to automatically patrol the recent changes based on their programming efforts.
