Steem is one thing, Steemit another :) While Steem may see itself growing, I'm not so sure about Steemit. I like it and use it but it'll only mature when the login, posting credentials management (keys) and the editor interface become usable also for the non-techy general public. Steemit still has a massive learning barrier that most people will not be able to handle without losing money, losing their account or simply become frustrated.
