I'm not sure I have the time and expertise to contribute well-written detailed posts that are of sufficient quality as to be top-level posts.

I think that was the point. I have no problem with WrongBot's posts, and I don't think they are lower quality than most others here. I suspect a lot of the reaction WrongBot is getting from a few people is because he joined and immediately made several posts about controversial topics, and people are wary of newcomers rocking the boat. If someone who had been here longer and seemed more familiar made them, I doubt anyone would have objected.
