Some ideas:
- Try posting at different times of day. Not everyone is in the same timezone as you.
- Post about STEM subjects, or go to an instance tailored to what you want to discuss.
- Look at which hashtags are popular to see what topics might be interesting to a wider audience.
- Go back and delete your "if you like X, don't talk to me" posts.
- Participate in other threads to advertise your presence so others know to follow you.

Seconding @design_RG, good luck!
