I think just being yourself is the best thing to do and say. The people who like what you say will upvote it. If people don't then that's not too bad. Either way you'll attract the right crowd.

And let's not forget that you'll be paid for it too.

If you want to earn well from this platform, create something and train to become good journalist/writer. Look at something like The New York Times, or one of your favourite bloggers - think Mr Money moustache for inspiration. Find your style. Find your mojo. And practice. You're not going to get a better platform than this to go for it.
