we have 100 people that votes

I'm not sure you are right... I'm voting every day about 40 times. But:

• I just have a small SP and my vote is nothing for those posts
• I'm not in your list because my voting reward is small (because I have a small SP)

If I will vote more with less voting power it still gives nothing to me and other users.

And there are many people like me.

So I want to make an update to your post. It is important that the owners of large SP have done more votes. So they get more rewards, increase the rewards to other users, create interest for new users.
