I think the thing about Wikipedia is that be the very action of Google treating it as an authority, even a less than authoritative page will almost certainly become one in a fairly short period of time.

People with an interest in whatever the subject is will easily find it, edit or add to it and it will evolve over time into something worthwhile, even if it did not start out that way.

A similar guess about a page on other sites would probably not have this effect, especially a made-for-adsense page, whose owner would be very hesitent to mess around too much with a high ranking page, no matter how poor it was in reality.
