Seth Godin has some ideas:
The Diggers, the posters, the surfers… these are very highly-leveraged people. Call them the Legion of Super Surfers. Okay, bad acronym, maybe not. Call them the league of the leading edge.
The leading edge has always been important. Now, though, since they have a megaphone, since Digg and the others are amplifying their movements, they are far, far more important than ever before.
And that’s Digg’s asset. They have aggregated the league.
So what now?
Get permission to fead the League tidbits about the future. The reason they are Diggers is that they like being first, they like discovering cool stuff and then sharing it. So organize that process and monetize it.
