One idea. Wiki markup gives headache to most/some (probably most) users and in contrary editing first message / posting new message is much easier. (Simple WYSIWYG and familiar editing system since dawn of vbulletin) So there should be same markup between wiki and vbullettin markup. Some WYSIWYG editor or some easy way to export messages to wiki. And maybe the BIGGEST reason why we do not see wiki much extensive editing is our user-base that is divided between maemo.org and talk.maemo.org. On that second when user is asked to register again after registering TMO probably most of people just leave it there and think WTF! Easy, Fast, Simple.
