Investors are not the most entertaining people, so social network can always do with some art, some babies, some jokes, some news, some science, some home builder projects and some kittens. I am not sure how the tribe thing will work. I enjoy to read all kinds of things, but these extra coins have made it possible to get some CCC on a post with no steem, so you can see that people appreciate it even though they are not steem rich.
