Recommendations for communities to join

Hi All,

I am trying to migrate from reddit to lemmy. Been using on and off for a about year, but now am considering to use it more now.

Would love some recommendations for communities to join? Especially in the following topics:

• finance
• investing
• movies & tv (trending + review)
• books
• science and tech
• aerospace and space engineering
• any other perhaps you want suggest.

Thanks!
