One of the ways to gauge the health of development software is to see the number of related jobs posted for developers. I spotted two Stencyl jobs today. They look pretty cool...
http://www.indeed.com/jobs?q=stencyl- The Bronx Museum of the Arts – In-School Museum Educator
- Manhattan Youth Recreation and Resources, Inc. – After-School Digital Media / Programming Teacher
I was also surprised to see that Minecraft was mentioned in both listings.

They're both part-time, so it doesn't look like a way to get rich teaching Stencyl. But if you're in the NYC area, it might be some fun side money. I don't know. If you are considering the job, you don't have to worry about me being your competition. I'm not planning on applying.

Anyway, it looks like Stencyl is on the way to becoming a standard tool for teaching programming to beginners. That's pretty cool.
