This forum will be the first medium to know about bitcoin wherein your friend can interact on do's and don'ts regarding about bitcoin. Youtube is also the best for it hence it has more videos about it and you can also explain to him directly that will certainly make him more interested about bitcoin.
Personally I referred them to search online especially watching some youtube videos just to grasp some knowledge and idea of bitcoin, thereafter I practicalized it by opening a new blockchain wallet using an android mobile phone, I did explained to them how to receive bitcoin in to the wallet respectively and show them where to copy their BTC address for transactions, I also show them how to send bitcoin to another person, this are some basic knowledge required by a newbie which I believe is very important.
for me, tell about this site is better than you just go online by yourself, asked by friend to do something alone is hard. because, from this site, you know not only bitcoin, and when you get paid, you forced to use wallet, checking transfer about that information, and other thing. you play a game, and learn the other that relate directly.
