This is a fantastic summary of why everyone and their mother needs to join Steemit.
Posting without any potential return on your time investment is silly! Even if you only get an average of $.01 per post, if you post 1000 times, that's ten dollars you wouldn't have had.
In the world of facebook, twitter, message boards, etc., you can post brilliant content that's extremely valuable to many people and end up with a few pats on the back, maybe a large following to market to, if you're lucky.
You can develop a large following, AND get paid while you do it in the process. Pretty damn cool.
