So true man, i also tried to convince a lot of people to join Steemit. But until now, there is only one who did. And he doesn't even blog, with the same excuse of the time and energy to put in it.
Anyway it is something that has to grow on you and you just have to start doing it. Someone told me about Steemit when it was launched and i did nothing with it for almost a year. I regret that now, so maybe they'll come around later...
