I've found from personal experience that having a bot-friendly page is just the first step in many that can deliver SEO results. For those interested, I've written a quick primer on executing a long term SEO strategy on Quora: http://www.quora.com/Marketing/What-are-some-of-the-most-ing...
And this is why I hate pg's policy of not showing vote scores next to a post. OP will never know how many of us upvoted your comment, thus he will likely ignore your comments because you are just @moron4hire. Without the context that comment scores provide, information like this is lost. If 500 people upvoted you, yet only 2 upvoted his comment, that would be an important signal/context IMO.
Agreed. I love Quora's newsletter, I like a lot of what they do, but I don't like their approach. It's enough to make me avoid them as much as possible.
