Actually it depends on a lot of factors:
- It's not the amount of votes but the weight of the votes. If someone with a lot of steem power votes you earn more.
- If the price of STEEM goes up you earn more (at least the equivalent amount in fiat currency)
- There is a "fixed" amount of STEEM created every day. The posts with the larger amount of votes (as described in the first bullet) get a larger piece of the pie.
- The blockchain pays out seven days after the posts are published.
The best way to earn more is to get more followers. So commenting on other people's posts is a good strategy.
Oh and comments can also earn you STEEM if they get upvoted.
Finally...welcome :)
