I like schvitzatura’s comment on Marc’s blog:
The true Web 2.0 Revolution was the rebuilding of the “walled garden” (softer, and with pretty little syndication bricks)…the technology exists but the business owners are still wanting to maintain “their own in their own”. Single-sign-on duchys and realms will still be the balkanized order of the day…
All this is is globalization, at the Web 1.9-2.2 mesoscale; the tribes will balk at any ham-handed introduction of interconnect.
This is why the Data Sharing Summit (which I’ll miss, regretably) is a right-track move.
Earth to walled-garden builders: You can’t own customers for the same reason you can’t own slaves: they’re human beings, and they want to be free.
Prediction: in Web 3.0, the best wall-less gardens will win.
