Two things I realized. An upvote of a new account is worth only 0.001 SP.

When new accounts upvote more than 10 times a day, the value of their vote turns to 0.000SP.

One has to limit oneself to ten upvotes a day.

The really insulting thing is that 0.001SP disappears as a rounding error when they calculate rewards.

Anymore, I only upvote a post when someone else has voted on it, because my vote disappears.

The game of getting accounts started is quite difficult. It appears that most accounts drop out in the first months because of the difficulty.

Quite frankly, the tiny pennies I've made from SteemIt is better than Twitter, Facebook and Tumblr. I've only made $7.80 for 220 posts ... but that is $7.80 more than I've made from all the other social media sites combined.
