The Q&A site Quora has become an indispensable trove of knowledge and expertise when it comes to the tech industry. Ask a question and get an answer - that is, after all, what all Q&A sites offer. But Quora boasts active participation from entrepreneurs, engineers, investors, designers, journalists and so on, so that the quality of the responses are quite high. Want to know, for example, why Foursquare uses MongoDB to store check-in information? Who better to answer than the company's engineering lead.

This weekend, Polaris Venture Partners' Ryan Spoon wrote a post on his blog, offering with a curated list of "must-read" Quora threads for entrepreneurs. Commenters on his post gave a few more suggestions.
