I think the mods here do a fantastic job, given the size of the forum, and the fact that you can never please everyone. I think the "Fill out your profile" posts are applicable and useful to those who join to ask a question, but perhaps not in the introduction / new user sub-forum.
Where a first post is made to introduce yourself with a bit of background, I think a PM would be more appropriate but there are a lot of first posts along the lines of "Mah camera don't take good pics" and there is no indication of skill level, camera, lens, conditions etc... so a post asking for even the basic info is very appropriate.
One fine example from another forum I recall, someone posted that they had been away from photography for a while, having just bought a DSLR - Their previous camera was apparently, an F4. They posted asking for help as the "Flash comes on and goes off"... The forum folk assumed they had a fair bit of knowledge purely based on the "F4"... It turns out the poster thought the flash worked like a torch and should always light a room, rather than, well, flash!... Go figure!
