Please see Wikipedia:Neutral point of view.  This huge article recently underwent drastic revisions to cut down its length, so that it is accessible to as large an audience as possible (Wikipedia is an international project).  The inevitable result is that its treatment of any particular topic will be light, bland, and superficial, but that's because, as a compromise, we've shifted all the treatment of all the complicated issues into subarticles.  For example, as a expert on the history of technology, I would prefer more treatment of that topic in this article, but I also concede that history of technology is a rather dry subject for most people and therefore I'm satisfied with the brief mention and links it gets.  Everyone had to give a little to make the current readable version possible; the earlier versions (check the history) a couple of years ago were really bloated.
