I don't mind commenters on this blog trying to catch me in a contradiction. Its actually kind of fun, because if you try to catch me in a contradiction and miss I get to try to verbally disembowel your ego.
That said, it would still be nice if someone would do so competently. Quotes and links. I've contradicted myself it a million times. Hell, I even gone into my own archives and done the work for you in the past. There's loads of stuff back there if someone really, really wants to catch me.
You have to read the entire post, though, when you do something like that. Telling me I said something when I spent more than one paragraph ruling that particular angle out doesn't really work very well even if you're just keeping to the current post.
Quality comments, people, I know you can do it.
