Some of the stupidest IT support conversations I've ever had have been with people who thought they could "undo" a mistakenly sent email because someone once sold them on an "Undo Send" option that was just a "Delay Send" option for X minutes. Try telling someone "No, you definitely sent that email" when they think, "No, if you'd let me use Outlook, I could summon that email back and it would disappear." I'm sure this idiotic "feature" will recur again and again as long as we have email and will inspire infinite fresh gems of magical thinking.

Why can't we celebrate how the Internet continues to resist freighting information with advertising? That's one of its best attributes.

Ironic that you can't actually read Mr. Pegoraro's comments. Sometime in the last five years or so it became easier to videorecord something than it is to write the same something down. Which may have something to do with the decline of newspapers.

I wouldn't want Representative Pearce's commute, and his huge district means long travel hours even when back home with his constituents. However, making Congress even less collegial than it's become sounds like a bad idea. There is a world of difference between negotiating on the floor of the House versus a 435-thumbnail Google Hangout. The effectiveness of your political representatives depends on them forming alliances, winning over opponents, remembering the names of their colleagues' kids, and generally treating each other like human beings. These relationships are still stronger when developed face-to-face, and probably always will be. If I disliked my representative's politics, maybe I'd like her to laze around in the district. But I strongly support her, and I'm glad she spends long days in Washington, DC doing the hard work that being effective requires.

I don't get why we're not planning to dock the shuttles to the ISS and leave them up there, too, with their useful engines, robotic arms, and so forth. The space museums would be sad, but someone would undoubtably think up some cool things that could be accomplished with them up there.
