GodBit has an interview with Scott Raymond about his use of Ruby on Rails in Blinksale and IconBuffet. I particularly enjoyed this bit about the opinionated software:
If you pay attention when you’re using Rails, you can hear its authorial voice. The Rails community calls the notion “opinionated software,” and people either love it or hate it. I love it. For me, working on Rails is sort of like having really smart, like-minded coworkers. It is inspiring, motivating and energizing.
