To start with:
why do people fellow others on steemit?
Steemit is a rewarding blockchain social network and people are rewarded by upvotes they get from likely, their fellowers.
This is the message:
Only follow people you will need/love to upvote, and simply do that . This will make the whole platform fantastic.
Taking up spaces following people and others doing the same with you with no reason dosen't make sense.
If you stand there and don't appreciate what you like with an upvote then who will.
If we all only stand to get rewarded without considering to assist others to get rewarded as well, then we are wrong.
Think about it!
