What do you mean, can be persuaded? Wikipedia is an all-volunteer organization. People here contribute because they want to, because they believe that this will benefit mankind.
They will also contribute if we show them how. I have several friends who are interested but who need showing what Wikipedia can do and how to do it by practical demonstration. I occasionally talk about Wikipedia in emails to people who might be interested. Its a sort of Viral Marketing, beloved of tele-marketers. Maybe we might have a campaign to 'introduce an editor'.
