As I've written before, I see the main "killer" aspect that can drive adoption in the Fleckroll list (which is currently called "examples" list, but could really be developed into something more central).
People who Fleck pages would do it again if they know their flecks get the headlines, even if for just 30 secs. That's the Digg factor that drives users to keep generating content, resulting in stickiness.
And Fleck does it very nicely, with a great creative UI. Boris tells me that a "most recent " filter will be added shortly, so you can see the latest flecks around the web.
