Well if any new people are interested in registering for coinbase. (not trying to be one of those spammers, but hey might help)
They have a referral thing where if you register a new account and buy $100 or more of bitcoin, the referrer gets $75 of bitcoin.
I'd gladly share 2/3 or $50 with people if they message me before registering.
I agree. I personally use Coinbase, and it's great as an online wallet service. The other awesome thing, as you mentioned is their referral service. On my screen, it states: "Earn $104 of bitcoin for every friend you refer who buys $139 of bitcoin or more." That's almost 1:1! Just me piping in.
