emsdc: There has been a little bit of skirmish lately about web standards issues on this forum. See, WP and this site and much of its active user community are strongly on the web-standarts-supporting side of this argument.
As for your criticism: If you get a "page not found", by all means point out the precise error. I agree with you that the available documentation is not yet in a very user-friendly format. Even as a relatively new WP user, I'm thinking about how I could get involved in that.
WP, bear in mind, while a remarkably capable program already (ie, it's by no means unfinished), has taken an incredibly rapid development in the last few months. See, for example the numbers cited here by one of its developers.
If you're unhappy with a commercial program's documentation, in most cases you can only a) swear, b) pay for tech support, c) hope to find some more or less sparse information on the web. In the case of WP, you can also get involved. So don't be a stranger.
