Hello all the professor steemian out there I have a serious question.
I understand that steem power is the key to decide your voting power but what does the number in the bracket tells u??
And how come I couldn't choose my voting percentage ( there's no sliding bar) when casting a vote??
It is a measure of reputation based on votes your posts receive. If you receive upvotes from powerful (more Stemm Power) users it increases your score. Down votes decrease the score. The result is that spammers with lots of downvotes will lose importance in the network and high quality content will be more prominent.
