You have actually demonstrates exactly what I feel is the main 
benefit of the "{foo}" syntax: Your example is missing a space 
before 'and'. This type of error is very easy to overlook with 
the ", " syntax, and much more visible with the "{foo}" syntax. 
The "%s" syntax also solves this problem, but at the cost of 
moving the formatted value away from the point of formatting.
