Wikipedia is pretty confused about what it wants to be. On one hand, "the sum of all human knowledge" includes a lot of minutiae that WP doesn't consider worthy of its servers. WP expresses that with notability guidelines. On the other hand, the extant notability guidelines means that a media blackout on you or your cause can keep you out of an encyclopedia that you really deserve to be in.
WP is an extremely political place. I was a relatively early editor and co-founder of an early Wikiproject. Ridiculously unnotable things like Unidan can slide because nobody really cares, but if you try to put something notable and controversial, but not necessarily widely known, in, you're going to have a bad time fighting off deletion requests and vandals.
It's not that nobody cares, it's that all that you need to have a page is 'notability' and notability is defined as having media articles written about you. If I can get the New York Times and one other publication to write an article on the spider that lives outside my front door, I can create a Wikipedia article for that spider and nobody can take it down, per Wikipedia policy.
