Just in case there are few Noobees who do not know what the Principal Bizz of Wikipedia Izz —
The principal business of Wikipedia is the construction of an Internet Golem that is capable of gobbling up all the Topic Turf that it can get its grubby cheeks around and controlling the direction of link-flow through that dominion.
As with any good Scraper, the quality of the content that it uses to occupy its topic turf is wholly irrelevant, so long as it maintains a highly trafficked corner of the web. Having users constantly fighting over its topic turfs is probably an easier way to achieve high traffic than it would be to maintain real-world informative but relatively stable content.
