One of the improvements in the Amazon Kindle3 OS is the WebKit-based browser. Based on a tip, I tried communicating on Freenode using the Webchat interface.
How do you get this particular OS update on a second-generation Kindle? Well, let’s just say it’s not officially supported.

Does the Kindle 2gen have a microphone? If it does, it seems like making a voice recognition program for it would be the best way to do IRC, so you don’t have to push those tiny buttons.
It does not have a microphone, unfortunately.
