Given the text blurring is a form of cloaking (showing one thing to the search engine, nothing to people who come in from a search) I think search engines should viciously rank them down too. And I don't care if there is some "easy" way to get around the blur (like the "scroll down" for expertsexchange or whatever it was), it's not obvious and it just pollutes the search results. Get rid of it. That said, as was mentioned elsewhere on HN recently, Stackoverflow needs a place for more meta questions to be moved rather than deleted as you can occasionally get a useful one that isn't just rehashing things we've seen 1000 times.
