No, I wouldn't check all of them. Really my vote doesn't matter enough.
I think it is bad for the overall system of building a social media site, but asking people to pay to have their votes seen. I don't think it will promote good content, I don't think it will promote better features, and if we want an advertising board, that is who will eventually have the money.

I didn't make anything personal to you or about you. So, if you like the feature and feel it is beneficial, please use it.
