I was randomly noodling on Facebook recently, when Philip Rosedale's head suddenly appeared, in an ad that offered me the chance to buy 10 minutes of Philip's time for some virtual currency. It's an offer on allthis.com, "the 10 minute exchange", which offers to connect you with "the greatest minds, celebrities, and leaders of industry" with virtual tokens you puchase on the site. (Write-up on Mashable here.) You can buy a token to talk with Philip (in this case) for ten minutes, but here's the hook: someone can buy that token from you for a higher bid. "You'll get back what you paid plus 5%," explains the FAQ. "The other 5% go to the person whose time is being traded." So if someone out-bids you, you still get a small commission. Pretty clever way of making celebrity access transparent, while also creating a market that shows how much that person's time is really valued. As for Philip, I checked with him, and this project is not related to his new start-up, Love Machine, or Coffee & Power, which operates on a somewhat similar idea. The founders just asked Philip to put his ten minutes up for auction, and he readily agreed. Now who wants to buy that token to talk with him?
