Serious question:

Should I follow more people on Farcaster?

My initial thought was the follow only people I knew IRL or have interacted with outside of Farcaster. 

I am starting to feel that this is close minded.

I would love to hear what your thoughts are on following count, pros and cons?

It is called Social Media not private media for a reason. Socialise more, talk to more people. On an average you would have to do atleast 3 new conversations to make/find one sensible friend. So don't shy away from talking to new people.
