I have nothing useful to contribute to the discussion, but I would like to say this conversation feels like Thanksgiving at my in-laws’ house.

My (uneducated) guess is that investing and doing business both tend to involve some amount of specialization, geographically as well as by domain and market, so a general purpose online setting might not be the place to go. Maybe classes at a local college or university or a conversation with a domain expert could be more suitable for your goals.
