I consider Steemit as a creator/blog platform, I prefer reading original posts, it seems to me there's no point on sharing something and that's it. Of course I don't flag anyone for that, I understand some people have the hability to write and some others haven't, personally I've written only one post since I joined the site a while ago. If you allow me a suggestion, you could write something about what you want to share and then share, not something "It's interesting" but maybe why you consider it interesting.
