I signed up for Google’s new App Engine beta and I’ve already started looking at the APIs. It looks very clean and well-designed. I’m not too familiar with Python, but it looks like it’s fairly simple to pick up. The language itself is easy and has some nice Lisp-like features that I really like. The hard part is getting familiar with the huge library of extension modules.
I’m thinking of possibly rewriting my2unz.com with App Engine, since Drupal can be really ugly when trying to integrate several third party modules with my own code.
