[Meta] Definition of the IXP initiative scope

@camoa Don't you think IXP (inexperienced) should be defined in an introduction on this issue?

Does IXP = inexperienced? That was hard for me to determine

Yes, Bob, I will do that. Or at least link the docs!

I updated the Summary to include a definition of IXP = Inexperienced.

I am creating a new child issue to survey and gather information from our target "Inexperienced Developer" audience, I think we should gather information from these folks about their initial career experience, what worked for them, what didn't work or frustrated them, and what ideas we should consider for our best practices.
