I did a few videos for Demand. Not worth the effort. I can make more money going door to door offering online video productions to local businesses. I was not qualified to write or edit for them. After only three books and some thousands of articles written, and eight years editing a well-known Web site, I wasn't qualified. Uh huh.
BTW - Patch and AOL's video production unit pay about the same as Demand. They're not worthwhile, either, unless you're really into formulaic work and barely earning anything.
