According to an article on ReadWriteWeb, Q&A site Quora is blocking search engines from indexing its site — all, that is, except for Google, Bing, and a couple other big players. If this is true, this is a really chilling development for the competitive landscape of the Internet.
Google is plenty big enough all by itself — just look at how difficult it’s been for Bing to claw out any sort of market share at all. I’d really like to think that the market is still open to someone who wants to build a better mousetrap, but this sort of behavior is going to make it just about impossible for a new player to break into search.
So take a look around — this may be as good as search gets.
