Yes, it does take repeated exposure. it took me a measure of awareness before i eventually joined steemit though @stellabelle's post. Some people even get apprehensive about huge amounts underneath steemit posts unlike you would expect. in my case for instance, in more than a decade of trying different means to earn my first dime online, i never earned. even tsu.co where i was before steemit crumbled before it could. i ended up joining steemit because i was looking for a home. One upon which dreams are buildable!
