Here's where you can get some more info about your current voting power, etc. On Steem it's similar to many games, when you are a beginner you have smal impact on the world surrounding you but over time, that would change if you invest in your character, either by work (creating and curating original, high quality content) and/or by buying more Steem and powering it up.
RE: Power up for newbies (Voting weight too small? Get more than $20 in SP delegation for free)
