My preference would be for the existing website - which has fairly good documentation about Teensy 2.0 and Teensy++ 2.0 - to be updated for Teensy 3.0 and 3.1. (Plus a bit of reorganisation, mainly to remove or de-emphasise the promiment non-Teensyduino section and the older products (MP3 player, etc) section.
I would be willing to help with this.
