From Economist report on social networking, comes this gem from a former Facebook employee:

“The people at Facebook are essentially utilitarians . . . They want to give people the very best technology for sharing and then get out of their way.”

Exactly right: great technology doesn't doesn't require you to interact with the people making the technology. That's why EpiSurveyor is the only technology that lets anyone create a mobile phone data collection system without any interaction with the people who make the software (us): simple, fast, free, online.
