Interesting article about principles for designing a successful web app... if you're the only user. There are zero references to security mentioned at all. As a security engineer, this bothers me a little bit. A lot of people don't understand that security holes in their applications aren't usually caused by a 0day in their framework, but instead sloppy security practices in the application itself.
