Short Comment:
There is also something to be said for the "social psych". The "social player" tends to have a preference for providing information. Which can help build a community exactly along the line of one that social players love, and their presence should be encouraged. But when those same social players stretch out to further aid the community by automating information (help files, guides, walk-thrus, sims) then it detracts from the socializing community that they desire.

Longer comment:
Business has had many decades of access to psychology papers on demographic types and how to increase or decrease their number. It might not be on purpose that online worlds have shifted to minimal help files with glaring errors causing players to socialize more in the game and to frequent the forums where ads are displayed. It might not be on purpose that fan-created help sites are not prominently stickied on official sites. But it also might not be entirely the mindless stupidity that players often chalk it up to. Everything has its Pros and Cons. (by the way, Experts and Gurus who give answers are another category, and also has pros/cons)
