I’m fairly handy and have hung drywall before. It’s not the hardest thing in the world, but you quickly realize a mediocre hanging job results in far more work by the mudding/taping crew. And the end result still probably would be OK at best.
Agreed, and I was exaggerating of course. There are definitely some handy people around here, but a lot of folks tend to underestimate what is involved. I've worked with a lot of beginners, and they can have a rough time just getting drywall screws to sink properly.
Like you said, it's not the hardest thing in the world, but it's not something that just anybody can do.
