> I knew about Drupal, CodeIgniter, Kohana, Symfony and Ruby on Rails.

I was a huge fan of PyroCMS which was based on Code Igniter. I stopped using it when the all of the JS frameworks exploded. I went back last year to check on them and found out they moved to Laravel.

The community since then has grown by leaps and bounds. Good to see the Pyro team still out there making a great CMS.
