For me, the Ruby community's comfort with monkey patching was a big turn off
It was definitely a crazier place 10+ years ago in the early Rails days.
Yeah! It sure was.
I was around, was an early Ruby and Rails adopter, and worked on a few commercial Rails projects at that time.
That's how I know about the monkey patching issues. Faced them in real life.
I played around with Rails and Ruby when Rails first blew up. But I didn't start doing it fulltime professionally until 2014. By the time it seemed to me that the community was maturing. I think it's in a good place now.
