I have openly shared, published online, gave away the store on just about everything I have created since getting into ed-tech in the early 1990s (c.f. “old dude”). I did this before there was a Creative Commons, I embrace and advocate CC, yet I don’t find all that much interesting in debating the various license flavors. While I understand the reasons for having so many two letter alphabet combos to string along after CC BY, frankly my dear, I think there are way too many of them. I’d rather be making stuff than dissecting licenses.
I could go with this…
