Did anyone look at the robots.txt? It looks to me like it doesn't block anything - it does have some specific settings tailored for various big-boy search engines, with a catch-all rule at the end for those not otherwise defined. It also says right there at the top "# If you operate a search engine and would like to crawl Quora, please # email info@quora.com. Thanks. " So they're trying to get the right data to the right search engines the right way - makes sense to me.
