I also see that each of these can have mini infograph [ sbd, steem etc] and as you get familiar with those, you can accept a more complex bigger infographic. I'd love to have those in my phone to try to explain to my friends how all this works :D

(in the works)

And I think you could give permission for people who hold bigger meetings about steemit to use them, I think it would be great :)

For sure, but there are still many "issues" and missing content as well as connections at current stage of gfx.
But it will definitely need approval before - this said:
