There's no hard definition of what is a good post, but you see people churn out Actifit or crappy photos with a sentence or two. That takes no real effort. They may still make something for that and so keep doing it, but they are unlikely to really earn. I think it is more about your audience. I want someone to read what I wrote or listen to my music. In this case it seems they did.

Okay, that makes sense, I have seen some of those posts I think. I was just really worried as I had just made a post that didn't really have a zinger to it. But many times I feel that way, so I would never post if I didn't say screw it. Thank you for the clarification!
