"Teaching What You Know" when what you know is no longer trendy

My two thoughts are:

1. Create something small (a 10 minute video, a long-form article, etc.) post it around in the relevant communities and see how it does.
2. Create a landing page about the larger course that the above mentions, and see how many people sign up.

From there, talk to people, see how you feel about the response, and then decide.

FWIW, courses are harder to make that I personally initially appreciated, so make sure you enjoy the work or can consistently make yourself do the work and feel good about doing it.

Just an anecdote to help point out that just because things aren't trendy, doesn't mean they aren't needed by a community that might be much larger than you realize.

I worked at a company called webMethods from 2006-2007. That's, what... like 13 years ago. I still get emails every once in a while asking if I can assist as a consultant for a webMethods project. I've gotten them for years since I left that company and the company doesn't even exist any more.

Remember, if someone ever used python/django/django (which we obviously know they did) that means someone has to learn and maintain it for a while. I doubt for 13 years, but at least a few years more.

You can try make a MVP, a simple, short but valuable enough tutorial. See people still interested or not.

Or you can do research on platform like udemy, does courses that teaches django api works well recently or not. Short it by date.

I don’t think those things are less trendy. You could showcase all the great stuff you get out of the box with Django that you have to build out with a framework like express (the admin site is awesome). Just make a good case for why learning Django or Flask will give you the same result as using express but will provide a simpler developer experience.
