Cool analysis. This is useful for exactly what this post is about – upvotes. Although upvotes are cool and make your account look important, engaging in trending/hot posts and providing good content with commenting is the way to gain respect between fellow Steemians that will eventually lead to more followers. Just posting popular images and memes won’t add any value to the community, nor allow your message to be heard by the right audience.
I am gonna follow your 20:1 rule from now on! Again thanks for the amazing post!
