Can't say enough about the quality of Nick's work with the Full Ratchet podcast (website, iTunes). Driving from Boulder to Aspen and back down was made infinitely more interesting when I discovered the podcast and hammered through a dozen episodes. Learned some new stuff, reminded of some old stuff, and enjoyed the professional, thoughtful, and disciplined approach.
As with all great works, it's a measure of how well something can be done. Let's all try to give back to the community like Nick's done.
