Honestly, until we see some improvements in the delegation of esteem system, and overall U/I I don't think you'll be able to. But the good news is this is improving and I'm sure steemit in 3 years will be totally unrecognizable and more welcoming to none tech/blockchain savvy individuals.
If this is a close friend sit down with them and explain how it all works right now and help/encourage them to create an introduction a lot of people become hooked after they come to understand how niche and "cool" steemit is
