I've had that same experience of refreshing to see if something is wrong, only to discover it's just that no one is posting. Seems so bizarre to me. For me how much I post is solely a factor of how much time I have and what I have to say. I never even think about the price of steem when deciding whether to post. I only think about it when deciding whether to invest.
You're just like me. As a student, my time is limited. I would love to post daily or multiple times per day but can't always do it.
I have a blast thinking up new post ideas. With Steemit, blogging is fun again! :)
