I have found the best way to get friends excited about joining is to share my posts on FB. I saw that you asked a question about eSteem and Steemit. Both are built on top of the Steem blockchain, eSteem is a mobile app. I recently posted this https://steemit.com/esteem/@melinda010100/esteem-app-79008201194ea Good luck getting it all figured out! Just keep reading and asking questions!
