You can't earn big out of nowhere, it takes time. I've been on for about a week and a half and I'm starting to get close to .5 on a good post or comment but not every one is going to be a hit.

Post more comments if you want to increase your revenue slightly but the only way to get big money on posts (fairly) is to put out good content over time so people notice you. I'll follow you to get you started so I can't wait to see what you put out next!
