An interesting and sarcastic (yet funny) article entitled Why your startup should use Ruby on Rails. All good points in there (for those too lazy to RTFA the point is really saying why you shouldn't use RoR), however I think a similar article could be written about your favorite language or framework. In fact, your favorite language sucks! :)
For anyone who has looked at RoR or Catalyst or any of the newer frameworks web frameworks available out there it's an interesting read. Amazingly the comments to the story haven't devolved into a flamewar yet. We can still hope though!
