Dylan Tweney talks about why he uses an application that doesn't quite measure up to his own custom solution. He doesn't want to try so hard to keep up with the latest changes in XYZ technology. It's just not important to him. I know how that feels. I just change my mind every other day.

Yes. Mostly.  Here's the scoop from the Movable Type FAQ.

MT version 2.0 and higher is free for personal or non-profit use. We're following a donate-ware model in which we ask that you send us a paypal payment for the amount which you feel the product is worth to you. In return, for every $20 that you donate, you will receive a Recently Updated Key. For donations of $45 or more, you are entitled to additional support. See here for more details.
