I agree with you
I didn't test it a lot, because I never expected much of it, but I did do some tests, because I wanted to know, to learn ... and you're right; it's pointless
it's too soon, that promotion button is only going to work once there are at least 100.000 users, which is still very low, while now we're at 10.000 users
but I do think the voting slider is doing a lot of good!
