I can't imagine any clearer signal that the freelance economy is happening than having one of the most successful business authors of past decade or so - Seth Godin - release a training class on becoming a freelancer.
The class is available on Udemy at a cost of $57.
According to an interview with Godin on the Gaping Void blog, here's reason he's done this course:
This is the golden age for freelancers. More opportunities, more tools, more leverage than ever before. But for many freelancers, there’s a big “but”…
If you are a freelancer, it may be that you’re underappreciated, underpaid and merely a cog in a system that disrespects you.
And it might be your fault.
This is a focused check up from the neck up, a chance to understand how to work your way up as a freelancer, by making hard choices and digging deep into the choices that matter.
I haven't had a chance to go through the course, but the guy's written 18 bestsellers. I think it's safe to say the course is good.
