Joi Ito's Web

Joi Ito's conversation with the living web.

John Poisson
I'm an investor in John Poisson's company Tiny Pictures which is the developer/operator of Radar. Radar is a cool photo sharing site for people who aren't exhibitionist weirdos like me. John and his team have worked with people like my sister trying to figure out the behavior of the mobile youth (and non-youth) and focused on the "Full-Time Intimate Community" (FTIC). FTICs are the close group of friends (usually around 8-10 people) with whom you share presence. Most mobile youths know whether members of their FTIC are awake, at school, happy, sick, finished with their homework, etc. They use their mobile phones to keep in touch with their FTIC usually sending state changes by text message. The idea behind Radar is to use photos as a presence stream to your intimate friends so you can share a richer presence and make short comments on the stream of images that show up in the "channels" from your friends.

Because of it's rather intimate and private nature, you end up snapping photos for their presence value over perfect artistic value and because of the private nature of the friends list, the content is also often more intimate.

I'm "joi" on Radar. Shoot me an email if you want to be my Radar friend. Like Twitter and LinkedIn, I'm only friending people I really know so apologies in advance if I don't accept all friend requests.

I signed up for Radar about a week ago and have been loving the service for the reasons you mentioned. It's the closed nature of Radar that makes it great, and communicating this is probably one of Radar's biggest challenges.

Thanks for the write-up, Joi.

I'll take the opportunity to shamelessly say we're recruiting for several roles, especialy mobile developers and web ux designers. Anyone interested should email us at for more information (no recruiters, please).
