I actually focus more on the "own your content" part, but always mention that every comment there can earn a couple cents if it gets attention.
But I think it's more about the lack of Portuguese content and the difficulties of managing their own keys.
Yes, the keys and the RC are usually the problem with me. I have them install Keychain in front of me, then pay for their account and directly delegate 50B RC to them. The only problem there was to get the keys from the cellphone to the browser, which I will ask the developers..
I put my promoter account with owning authority over every account I create because is very easy to common users to lose their keys.
When they are mature enough to know how to administrate their own keys they can use tools such as PeakD to remove owning authority.
