The Core Mechanic is now available to Kindle users via Amazon's WhisperNet technology. They have priced it at $1.99/month, delivered straight to your Kindle. Had I been given a choice, I would have preferred it to be free - but that's the lowest they will go for Kindle hosted blogs. I guess it's mostly to cover the cost of WhisperNet or something.
In any case, if you want to help support The Core Mechanic and happen to be a Kindle owner, click the link on the right and subscribe!
