Freelancers -- where do you find most of your work?

Agree with Steve (in fact, I think I always agree with Steve!)

I think that tools like Articulate have opened up an interesting ecosystem of related/supporting products services.

One of the things to think about is: service based freelancing, which is what the original thread was about or product development. They are two different paths and I would suggest that you need to do one or the other.

In terms of services, you could provide services to instructional designers, and they call you for projects that need something customized. And you market yourself as the preferred coder for instructional designers who might want to kick things up a notch on a particular project. Those are your clients (people like Daniel, Bruce, Kevin, etc)

Or, you take a product approach like James Kingsley http://frameentered.com/ or Bryan at elearning Art http://www.elearningart.com/  have done. Build a product that would make lives easier for articulate storyline users, bits of code that would speed things up, different skins, etc.

Either way, you should look through the forums and figure out: "is there something that people ask for commonly that I could easily offer" and explore those. Maybe you can re-focus what you are good at already rather than switching completely. 

Hope that helps,
