I've been learning how to use WordPress for the last few months or so and of course, I'm loving it. In the course of this I've become pretty familiar with the codex and documentation covering WordPress.
The tutorials and help here are very, very useful, and I've learnt almost everything just from these, not by asking through the forums etc. What I've noticed however is a lot of this documentation starting to degrade... organisation could be better but the biggest thing is that as WordPress development speeds ahead, the codex isn't keeping up and its full of crossings out, 'notes', 'link rot' and out-of-date information.
Its a good resource, and when I look at the volume of people clammering for assistance in these forumns, making it a little easier to use could make things a lot better for everyone. Just about all the questions people ask are answered in here... its just sometimes a little hard to find.
