I've personally given up on editing Wikipedia (too many fanatics with infinite time), but IMHO it needs to be much more deletionist than it is now. There is value to its current wide scope, but its maintenance model has trouble with long tail articles. It shouldn't have an article unless it can consistently gather medium-sized quorum of active editors to watch over it.

This was the ethos of the project in the beginning but is not the ethos anymore. People have realized how valuable it is for companies and other actors to have their own article on Wikipedia. Therefore Wikipedians have created a very bureaucratic system for deciding which articles should be created. And people like to wield power. For example, by rejecting perfectly good articles.
