I don't have as much of an issue with the jokes. My issue is when I try to add (as in not changing) to an article and my addition is deleted without any explanation whatsoever. My only successful contribution to the wiki was a single line that I had to fight for, I don't mind discussion and someone making comments on the validity of my addition but someone just coming along and deleting stuff without explanation is what I am complaining about. I only got feedback on why my line was deleted after I demanded one and even so the response was "I never heard of this so it must be wrong". At the end I managed to maintain my wiki addition but the attitude I encountered while doing so was something I did not appreciate. The attitude read as someone who is either over protective and defensive of the existing content or doesn't allow anyone else but 'the trusted circle' to edit it.
If there is disagreement about a change or addition, that is cool and fine, deleting without any explanation is not.
I am not really all that concerned with the wiki, I gave up on it ages ago as a fan wide community project, I just wanted to voice my concerns. After all, in these sorts of projects, criticism should be welcomed not rejected.
