I don't consider you unfit for editing the wiki, I consider you unfit for leading (or shaping, but leading is more actionable) an effort that brings a lot of new content to the wiki.
I am glad to see your wariness. I was getting a bad feeling when David_Gerard started presenting himself as a wiki authority - especially when it came to editing content. The one time I recall David referencing his wikipedia editing I was appalled by what he had done to the page. It actually lowered the extent to which I am willing to trust the content on wikipedia when it comes to pharmacology. The scary thing was that I would have taken it at face value if I had not already searched pubmed myself.
I have no doubt David has much to offer in terms of wiki management skills but the potential for a dominant influence over content creation specifically was scaring me. (Just not enough that I was willing to volunteer to work on the wiki myself. The wiki is not quite that much of a priority.)
So, as people have probably noticed, there's fairly regular vandalism on the LW wiki which has been taking a while to address and which regular users have been trying to cope with by moving and blanking pages. This is a little silly - it doesn't resolve the problem and just generates more noise in the RSS feed for Recent Changes (to which I've long subscribed).
We need more administrators.
I suggest myself. I'm a longtime LWer with high karma, so I can't be too crazy. More to the point, I currently handle vandalism as an administrator on the Haskell wiki and have done so ~July 2010; I was formerly an administrator on the English Wikipedia (where I have been a contributor since ~2005); nor have I abused access that has been given to me elsewhere (eg. my shell account on http://community.haskell.org, the commit bit on the PredictionBook.com repo, etc.). In general, I think of myself as a wiki-savvy and trustworthy guy.
Administrators are created by bureaucrats; there are currently 3. Rather than simply message Yudkowsky or Matt of Trike, I thought I'd make my request public along the line of Wikipedia's Requests for Adminship.
If people object, please leave comments; if there are any other users who would like to be admins (David Gerard comes to mind as someone I know from Wikipedia and would trust as a LW wiki admin), likewise.
