Having gone through this and this page, I don't really see any influence of jokiness within full job articles (of importance). I haven't scoured every single one, but everything so far has seemed within reason past a couple of outdated mechanical references such as loyalty implants.
The tone seems perfectly fine, as noted the only issue would seem to be that the wiki understandably doesn't keep up with every PR ever made. There's nothing wrong with sharing in the good humour of other servers, especially if it'll make newer players feel more welcome.
