Back in 2002-2005, I knew a whole lot of "tech-savvy" people with top-notch pedigree, who never believed FB/Youtube/Twitter etc would scale as no one had ever built a "many-to-many", pseudo real-time network at that kind of scale before (both technically/financially). Let alone a bunch of 20 year olds.

I was quite convinced by their arguments. Where I was wrong was believing technical arguments mattered.

What matters is the psychology of the herd.

The worst group to validate new ideas against are developers.

Pretty much. They'll tell you a hundred reasons why any single idea you have could never work, for technical or other reasons. I say this as a developer, and I've been guilty of this before.
