Simplicity = Speed
With the popularity of cameras like the Flip, one thing is abundantly clear: people want stupid-easy solutions to get video onto YouTube. The Flip is a camera that records to internal memory, with a flip-out USB connector. Acting like an external drive, you can now upload the properly formatted video--no editing or encoding required.
There's a quality issue, of course, but YouTube is proof that people have become desensitized to quality and it isn't really an issue. What is an issue is how fast can you crank out content that will add to your overall page (or channel) rank?
Even if you don't own a Flip (I want my manual features!) there's a lesson to be learned here. If you can record everything in one shot with little or minimal editing, you can post content daily and it won't even take much out of your life. If you want quality, you're going to have to spend some time in post, but if you can figure out how to do a good or useful show simply (which equates to quickly), lots of content on a regular basis is more than a reality.
