Hey @charles1
I think many people won't join it because people are afraid to loose, they are skeptical, and they are habitual to their daily routine of entertainment.
There are thousands of books and websites on how to make money but very few people are interested in it.
People want to earn money but they jist just wish and don't take actions.
Good point, I agree with you. However if steemit can get 1% of the +2 billion social media lovers, then we will have millions of members and many willing to work hard...price of steem will shoot to the stars
