Maybe we were just too early.
When I first wrote that post, years ago, I expected most people to ignore it as tinfoil-hat stuff. But as time has passed, people are becoming more aware. (Also, the implications are becoming more costly.)
I no longer write off the non-technical public as "they don't understand/care."
This gives me hope that alternatives can work, even alternatives that require network effects. (Though, I think the best alternatives won't be another social network but something more akin to easy ways for people to run their own group communications. I don't think a me-too will win here, but something more of a leap-frog.)
