TPM Reader FF writes in with a mild (and probably justified) complaint, but that's not why I'm publishing this email:

I think you need a better weekend strategy; a guest blogger, a regular weekend feature (you could have Eric prepare it mid-week) something to satisfy the fix of your regular readers and advertisers ... This weekend I was hanging from a harness on Yosemite's Half Dome, but I had a fair bit of free time belaying and a strong 3G signal (coverage is very good in the valley, the RV/diesel generator crowd would stand for no less) ... it's a new and ugly world.

Amazing. The only thing that gives me pause is the thought of my belay partner surfing the web somewhere down below me, with my life in their hands. My own rock climbing experience (such as it was -- you'd never have seen me anywhere near Half Dome) mostly pre-dated cell phones.
