It seems to me that Wikia should be an effective disruptor, but it isn't and I'm not sure why. Culture? Stigma? Awareness? Reasons I think it is: it's very domain-specific, which makes it possible for qualified editors to flock to appropriate domains; there is a separate command structure per Wikia, enabling access on a per-qualification basis; it practically begs you to copy content from Wikipedia as a base; it already has a financial support system in place with the ads, and presumably has solid infrastructure backing it. I can see how some of those strengths would double as weaknesses, though.
