My answers:
I kind of invented Steem after learning about cryptocurrency. I've been thinking, what if Facebook likes were a currency? Then I've asked a friend who is deep into crypto and he pointed me to Steem.
I think I need to make some tangible success on Steemit to recruit anybody. So far I see it as my own adventure and responsibility.
Steemit is a living community of bright people where one's voice can be heard and for me it's the main point about why I am here and why I want my friends to be here.
