If you want to see someone else, or think that they don't deserve to be there, then post amazing quotes, follow more people (you're more likely to get followers that way) and be patient. But don't be rude. That's not what Witty is about, it won't get you followers.
No, god no. I should have put and it won't, but no, it's not about followers. However, if you're saying that the same people are on the top quotes every day (or implying it) then the natural solution would be to get yourself there, because you can't really complain about it, so one might assume that you want to be in the top quotes, therefore you want more followers. No, Witty is about expressing yourself, but in a way that isn't rude to those who work hard to get where they are.
Getting the honor of being being the one to write a top quote boosts peoples self-confidence. This is breaking it down. Don't turn Witty into a half-baked vanity project!
They can't help getting as many faves. They post quotes, they get faves, Big deal? I think not. Get over it. There's no need to hate anyone for getting top quotes, jeez.
