I was in an interview once and the prospective employer asked me what church I attend. I replied, "Catholic." He said, "Is that even Christian?" So, yeah, plenty of Americans have a skewed view of Catholicism.
I had the opposite experience coming from Django/Flask to Elixir/Phoenix. I found it very comfortable and that there were many similar patterns at the framework level. Now, LiveView is a bit of a different story but basic Phoenix routing and views seem quite similar to Django routing and views. Ecto's model schemas have a decent amount of overlap with Django's model objects.
Was it the LiveView stuff that felt foreign? I'd agree there's a learning curve there as someone coming from Django.
I recently used ChatGPT and Claude to help myself build a simple app for my wife. Just listing things and being able to edit them basically. It was VERY frustrating as both models get pretty basic things wrong around the plumbing stuff like configuring SwiftData or CoreData.
I tried it with a version of the prompt(s) I used in that project and I got an app that's just a white page.
I think your best bet is to catalog them (using LT if you like) and try to sell them as a single collection. If there are any that you identify as particular powerful, maybe sell them separately. What's going to kill you is the shipping for a single collection. Maybe offer a discount for a local sale and pick up.
