I know this is a little nitpicky, but your Python example has way more brackets than are strictly necessary. if post.created_at < datetime.now() - timedelta(minutes=5): I agree with your argument in principle though. Just wanted to point out if you're trying to make a point about readability / ease of use with code examples, you should try as hard as possible to make each example optimized to avoid accidentally creating a straw man. Also, one criticism of the Ruby version is the invisibility of the types involved. What type is returned by 5.minutes vs 5.minutes.ago? How do I know I can compare the second to a date attribute from ActiveRecord? The Python version is more verbose, but I think it's more clear that I'm using two datetime's and a timedelta.
