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.
Your advice is worth about as much as your steem power.
