@onelife4oneworld, my wife can't wrap her mind around stem, yet.
Start connecting with people by commenting and answering replies. Once you get some followers who are interacting with you, then I think that you should ask your wife to run an experiment with you, maybe 3 weeks to start.
Repurpose some of your wife's existing content, and let her see how well it is received on Steemit.
Then ask that she write something original for Steemit.
I would recommend building a following first so that you can see some traction for the first few posts that she is a part of.
wow...great advice
I second that, a three week trail will do good.
