We'd be curious to know how often Quora is indexed by Google; if we had to bet, we'd say it’s less. Part of it because the site is younger but part of it, we'd surmise, is because Quora’s more open-ended questions overlap less with what people are actually searching for. And although it’s early days for both companies, it’s a hint that the most hyped company is not necessarily the one that ends up with the most success or the best business.
I've been liking Stack Overflow a lot more than Quora for a while now. Looks like I'm no longer alone.
