In the world of skinning, the # of creators to consumers has, over time gotten to the point where it's nearly all consumers and almost nobody is creating the content.
I'm seeing a little of this in blogging.
Joeuser's traffic has been improving at a pretty good pace as the servers have gotten faster again and the reliability has improved. But there's fewer new blogs to read through. Of course, weather is getting nicer and we don't promote JoeUser for new bloggers, but it's still an interesting trend.
