Well reddit is also a lot of this when you dig in the smaller communities. Sure, if you stay on r/AdviceAnimals you are bound to be disappointed ;)

There are tons of cool communities but none that I've found yet about starting a small business or similar. If you know of any along the same themes as HN then I'd love to join them.

/r/startups /r/Entrepreneur /r/smallbusiness

... of course, you'll find plenty of reposts from HN.
