Woohoo, someone just made a nontrivial edit to it!
But other than that, it seems to be mostly flying under everyone's radar. I hope it doesn't get deleted, but it might for being too niche. If it does, I guess I'll have to find a statistics wiki to move it to. Most of Wikipedia's deleted niche content ends up migrating to wikia or similar.
The point is: your article can get nuked at any moment unless your article is about a topic familiar to the Wiki Admin demographic OR unless it has a defender (a powerful enough Wiki Admin who will monitor and stand up for the article).
That gives me an idea. Wiki Admins should offer a paid service! Pay me monthly and I'll actively protect article(s) of your choosing from deletion or vandalism!
That's almost worse, since the results are so haphazard. Outside of a few predictable topics (virtually all cities/towns get long-lasting stubs), Wikipedia is "comprehensive" only to the limits of "no one noticed, or someone powerful stepped up to defend it".
