100x bigger platform

Anyway, it's not just about the nature of blockchain, I reckon. It's the style of site. Steemit is not = reddit. It's more akin to Wordpress, and if you see comments on wordpress, it's basically the same kind of thing as here, including friends who mostly comment on friends.
Because the format here is different. You're trying to build a personality, a character, a story of a being that people get to know and love/hate. In reddit it seems to be more like a one-hit-wonder kinda place, or like a public version of your facebook feed or something.
