Over the years I have learned from the following resources:

- Easy to follow guides for understanding financial instruments in the personal context.
- reddit.com
- from niche to mainstream, anything can be found and discussed here. Moderation and quality of the content might be inconsistent due to the size of the platform.
I keep up with the flow by subscribing to these streams:

- lobste.rs has a smaller community with stricter moderation when compared to hacker news.
