I agree, I think it depends on what the focus of the activity is.
A while back I made http://crimesagainstcode.com/ as a weekend hack. It's built on Rails 3.1/CoffeeScript simply because that's was I was also playing with at the time, but the "hack" part for me was the fiddling with QR codes in a pretty obtuse manner to see what I could safely manipulate, not the underlying technology of the site itself.
