The (Wireless) Dead Zones
The biggest surprise in all these reader reports was the number of people who expected their (non-Verizon) phones to work in the subway and were annoyed to find that they did not. Verizon has been the only carrier to offer service underground in Metro for years; some AT&T and Sprint phones can roam on Verizon's signal, but that's it. This isn't because other carriers are barred from offering service; it's just that it's hideously expensive and slow to string wires in tunnels that happen to be occupied by large, fast-moving trains for 20 to 22 hours a day.
...Digital TV rocks! Last week, the Federal Communications Commission launched a strange site, DTV.gov. The idea is to offer advice on the ever-confusing topic of digital television, but in this case the site looks and feels much more like a straightforward ad.
Lastly, one quick note to readers who use challenge-response authentication systems (such as the services offered by EarthLink or MailBlocks): While I applaud your steadfast defense against spam, I also want to be able to answer your e-mail without jumping through hoops. So please add me to your allowed-senders list if you want some sort of a response. That should happen automatically if you send me mail, but there are evidently some challenge-response systems out there that don't take that step.
