Steve Yegge in an epic rant about Google Plus and his time at Amazon:
When software – or idea-ware for that matter – fails to be accessible to anyone for any reason, it is the fault of the software or of the messaging of the idea. It is an Accessibility failure.
Like anything else big and important in life, Accessibility has an evil twin who, jilted by the unbalanced affection displayed by their parents in their youth, has grown into an equally powerful Arch-Nemesis (yes, there’s more than one nemesis to accessibility) named Security. And boy howdy are the two ever at odds.
But I’ll argue that Accessibility is actually more important than Security because dialing Accessibility to zero means you have no product at all, whereas dialing Security to zero can still get you a reasonably successful product such as the Playstation Network.
