Hey there! I completely understand what you mean. It was pitched to me the same way.
I see this platform more like reddit or tumblr. I think it has a long way to go, but theres definitely a sense of community and building a following based on what you post or repost. Just with the added bonus of earning some money. I think it also depends on what your posting about, some tags arent super popular yet, so it might go unseen in that instance. But in saying that, I dont think you shouldn't post what you want. At least thats what I am doing anyway :P All the best on the adventure, I hope it turns out to be what you hoped!
