Sooth is a social-psychologist founded company that develops community around the art of giving and receiving good advice. Their IOS platform app brings users together for anonymous advice-asking and advice-providing. Despite anonymity, and due in part to the educational materials provided to users, advice tends to be very high quality. I encourage you all to check it out!
For my own contribution, see:

I describe obstacles to giving good advice – including confirmation bias, the illusion of explanatory depth, and passive dehumanization. I then recommend some research and experience-supported antidotes.
