I've finally got an account in Quora . Google Groups once captured Usenet and now Quora is capturing the market. Right now, my profile and activities are in stealth mode. The information is quite addictive. But, I couldn't still find a button to link to Quora profile--something like Twitter's follow button or LinkedIn's button. I think, Quora is yet to focus here on promotion.
