Because who I follow will result in their posts in my feed (which is the intent and purpose of following someone) I look at the last like 5 posts the person made to see if they're worth following.

But I think your method is intended Twitter behavior. I never used Twitter on the regular. Your method is like social approval follow the heard mentality which may very well be the strategy for a successful content creator, but my method is a very selfish "do I want to see this persons posts in my feed" lol.
