Pyramid really is the underappreciated hidden gem in Python web development. It can be as much of an micro- or full stack framework as you need it to be, while being much better thought out and extensible than something like Flask or Bottle. No crazy thread local state imports to complicate testing and encourage people to couple their code to the web framework, features like renderers to make _unit_ testing view functions easy, almost 100% test coverage in all the core libraries... It's a shame that the mainstream basically boils down to Django or Flask. But it's no wonder that organizations like Mozilla and new PyPi are building on Pyramid instead.
