When I read articles like this, I always wonder if early-on there was someone in the room saying "Um..guys..maybe we should just pick something stable first?" and got shouted down as being a Luddite?
I've seen that countless times where exuberant "experts" hastily choose a new technology over the warnings of those who are a little more thoughtful in their technology choices. Usually the ignoring comes with a heavy dose of disdain and mocking of the person for not being "up to speed with the latest stuff".
Then when disaster strikes, they seem to have forgotten about how they were warned and write a blog post about how much smarter and more experienced they have now become.
Not suggesting that this the case here, but I have to wonder if Cloud9 didn't have at least one person saying "Whoa there sparky! Have anyone of you considered how we are ever going to query this stuff?", etc.
