In my (not) copious free time I’m helping out with Dopplr, a share-your-trips travel site (my title is “Founding Traveller”). It’s getting more attention, with recent funding news. CTO Matt Biddulph and the others on the amazing development team are busy adding features and making the service more useful. It’s still invitation-only for the moment, but if you want an invite, give me a shout.

Meanwhile, kudos to Martin Varsavsky, the founder of FON, a Madrid-based startup that’s trying to seed the world with a bottom-up wireless network. (I’m on the board of advisors in the U.S., and could eventually benefit financially if the company succeeds.) FON just signed what could be a breakthrough deal in the U.K. with British Telecom. Congrats to Martin and his team.
