I realize normal is arbitrary (I'm definitely
not normal!), but at some point it should be defined for the purpose of deciding what to pursue for the sustainability of a system.
Anecdote: The Moodle support team at our university told us at a meeting some years ago that 100% of Moodlers were using Moodle to distribute course content, that some lower percentage <50% were using quizzes, and nearly 0% were using Workshop
activities. Their conclusion: do more training on workshop, since it's a great feature that's just being under-used.
My conclusion (having tried it!), it's a great feature, but the problem is how to work it into a good pedagogy (something the Moodle training people fail at, because they mostly do IT support).
The reality is (as sad as this may be) a majority of the Moodle users will never create a Workshop, yet the source code, the tests, the application logic that is inside other classes, etc. remain and have a "cost" to the Moodle project. They take up time and energy, making the overall project harder to understand and extend.
Now, take the same idea and apply it to those 20+ options to configuring a quiz, the numerous question types, the support for old browsers and versions of Moodle, etc. It's not about babies or grownups, it's about focusing a limited (open source) energy onto the things that affect the most users in a world where IT is changing super fast. I think it's what's happening at Google and Canvas and who knows what else.
Meanwhile, this semester's experiment is going very well with my course using Google Classroom. Do I miss the pedagogical value of customized feedback on wrong answers in multiple choice questions in Google Quizzes? You bet! But I'm also super happy not to have to give bonus points if students ask questions in the Moodle forums (which they hate). They're using comments in Google documents to ask me questions on the text they write (so much more precise). They ask public questions in the classroom "feed" (like Facebook) on the work I assign them. Those things have way more pedagogical value (to me) right now. Plus, the clicking for me to set things up is so much less.
I realize I'm ignoring the "freeness" aspect and it's not an entirely fair comparison, but this is the real world.
