Your Vote Value
From: https://www.steemnow.com/

As you can see my 100% vote power equates to a whopping $0.01.
This should not concern you. A vote is a vote, and eventually your vote will be worth a lot more.
Your Voting Weight:
From: https://steemd.com/@bashadowTotal Voting Weight is the amount of Steem Power (SP) you have either earned, or given yourself plus the amount, (if any), of delegated Steem Power. When I did this snapshot I had 124 Earned Steem Power and 14.6 Delegated Steem Power.
What the Picture says:
STEEM POWER
Influence tokens which give you more control over post payouts and allow you to earn on curation rewards.
Part of your STEEM POWER is currently delegated to you. Delegation is donated for influence or to help new users perform actions on steemit. Your delegation amount can fluctuate.
The amount in ( ) parentheses is the "Delegated Amount"
Please note these words carefully : "Your delegation amount can fluctuate". People and the system giveth, people and the system taketh away. If it is the "System" I can not help there, I have no idea how or when or why or even where the "System" delegated steem comes from. I am not sure anyone really understands it.
Maybe we will get lucky and some will tell us in the comments section.
If a Person or a group of people give you some Steem Power, you can always ask them why they gave and why they took away.
Your Voting Power
From what I have been reading you can vote up to 10 times a day before your voting power falls out of the 100% upvote range. (this does not mean you are limited to only 10 votes, just that you fall out of 100% range.)
Voting Power decreases with each upvote. At 100% one upvote will decrease your voting power by 2% per vote.
Your Voting Power recharges at a rate of around 20% per day.
@scrooger recommends:1
"Don't drain your Steem Power to levels below 80%. Your votes will have less effect the lower your Voting Power goes. Instead, take a rest. Go write that post you have been thinking of and let your Voting Power regenerate to ensure your votes and rewards have maximum effect."
[Which is why I am (@bashadow) writing this post.]

So how do you build Steem power
You build Steem power by earning Author Rewards or Curation Rewards. Author rewards are upvotes to Items that you have posted. Curation Rewards are votes you give others on content they have created. After getting a few rewards you want to build your Steem Power. To do this:


You will need to use your "Active Key" to complete the transaction. In 3.5 days return to your wallet and Power up.

Do this every now and then and you will be well on your way to building your Steem Power.
I still have a long ways to go before I get a Slider, but every week I get closer. There are a lot of steemit blogs on getting seen on steemit. You can do a google search: "steemit getting seen" and get literally hundreds of Steemit post, giving advice on it.
Voting power slider
When you reach approximately 2480 SP, when you go to vote on a comment or on a Blog/Post you will have a slider pop up and you can adjust how much weight to give your vote.2Per: @xervantes post from 6/20/2017:
The Cost of a Vote
The rewards associated with a vote do not come out of your wallet. The penny that your vote is worth will stay in your wallet. No money comes out of your wallet to make a vote. The money in your wallet stays in your wallet unless you send it somewhere.
Be very very careful with your wallet. Never give anyone your "Active Key", or you "Master Key". I don't care who they say they are. personally for myself I will never Click on a link in the wallet remarks section. 90% of the time it is going to be a scam or a phishing expedition.
