The investment fidelity of this information is likely pretty high - not necessarily with this analysis ... but investment picks from topics popular on hn (ex: tesla, bitcoin, apple, amazon[ec2]) were ahead of the market.<p>Products, services, or companies repeatedly lauded in the comment section, in my experience, are remarkably indicative of future broader trends.<p>For instance, this user, in 2010, lamented about the rampant bitcoin discussions as excessively overflowing on hn like some irritating internet meme: <a href="https://news.ycombinator.com/item?id=1998630" rel="nofollow">https://news.ycombinator.com/item?id=1998630</a> ... at the time of posting, bitcoins were selling for $0.06 each. Would it have been a smart idea to buy 10,000 after reading that? Probably.<p>I can imagine an arb-style subscription to the right sql queries could be packaged and resold for extremely good profit to the right people.
