Social Content

As I talk about the BIG VISION for BricaBox, I often find myself repeating a definition for "social content website" -- because that's the scope of our platform, and those are the kinds of sites we set out to power. Currently, my best definition of "social content" is this:

"Websites where a group of people collaborate on a base of content."

While I've thought about including a qualifier like "... using a common format" to the end of that definition, I think it's pretty good right now.

Here are some examples of "social content" sites, so you can see the scope of this genre:

• Wikipedia is a "social content" website
• YouTube fits this bill
• Yelp is an example
• Scribd is a social content site for documents
• 43things is a social content site
• Digg is also a social content site
• Aviary is a social content platform

What's your definition of "social content sites"? Have you ever thought of all these sites being under one genre?
