I agree with you my friend!
It would be really nice and explosive if a celeb / highly influencing people is coming to steem and promote this blockchain in the world outside. That would be awsome (just like you :P )
Although I am in my bubble on instagram I am promoting my content there with steemit-link and my video thumbnail if it could be intersting for the people following me there.
I am doing it more and more from now on because I got some likes by people - I know they dont use steemit.
side note:
I have such a phone suction cup for the front window and this is rly the best solution for me to make cartalk videos. You should check this out my friend. But the perspective is kind of intersting also ^^
