Trading is mostly a zero-sum game so people are going to be selective about sharing useful ideas. For investment the horizons are so long it's hard to know which people are worth paying attention to. Maybe some people try to influence sentiment on reddit but in general most successful financial professionals don't spend their time posting on message boards.

Anyway, I don't think it's realistic to become good at trading/investment while working in a different profession. Be prepared to drop everything and focus on it full time (after a few years of preliminary study) if you're really serious. The learning curve is a lot worse than tech, and it's not just because there are no tutorials to learn from. The level of competition is completely different.
