O’Reilly Network: Ruby on Rails: An Interview with David Heinemeier Hansson:
“That’s not necessarily an easy sell, though. Just see all the wars through the times over coding standards. If people could just agree on one way of placing their brackets, they could presumably reap more readable and uniform code. But for a lot of people, that didn’t work because the trade wasn’t appealing enough. Getting a more uniform code base is frequently not treated as importantly as individual ‘freedom’ by a lot of programmers.
Rails essentially tries to do the same as the coding standards did, but the reason it’s working better is that the deal is much sweeter. Getting a uniform code base is an abstract, group-centered goal. Seeing your application work in a fraction of the time it took you before is a very concrete, individually rewarding goal.”
