I agree that contributing is a little daunting –?I’d feel more comfortable with something like PHP/Flash docs, where you can comment underneath a page and there is moderation/admin responses if necessary. That way semi-pro people can contribute without the fear of getting it wrong. I know there are user pages but keeping everything in 1 page is more concise/readable IMO.
As you say, lot’s of peeps posting then finding their answer shortly after! I do hope WP adds a ‘newbie’ section… I completely agree, everyone is getting lazier myself included, but I think the basic WP search functions are exacerbating the problem.
It sounds shallow, but the UI/graphical improvements in 2.7 really made it stand out for me! All the best
