Web geeks have long fantasized about a Web taxonomy, a classification scheme that would encompass the entire Web--not just sites, but also content such as images and blog posts. The hierarchical directory set up by Yahoo Inc. is an impressive attempt at a kind of Web taxonomy, but it's a weighty construction that doesn't make finding things on the Web all that much easier or faster.

Even worse, it's a classification scheme that has been imposed from on high by Yahoo's information mavens. But we now live in the age of the long tail, the collective influence and power of the small sites and users that make up the vast majority of the Web. The big corporations like Yahoo or Time Warner Inc. might make up the "head" of the Web, but the hundreds of millions of personal sites, blogs, BitTorrent peers, and Flickr photo albums--not to mention the hundreds of millions of users roaming the Web--comprise the beast's massively long tail.

How the FCC Settles Radio-Spectrum Turf Wars

Remember the 5G-airport controversy? Here’s how such disputes play out

The airline and cellular-phone industries have been at loggerheads over the possibility that 5G transmissions from antennas such as this one, located at Los Angeles International Airport, could interfere with the radar altimeters used in aircraft.

You’ve no doubt seen the scary headlines: Will 5G Cause Planes to Crash? They appeared late last year, after the U.S. Federal Aviation Administration warned that new 5G services from AT&T and Verizon might interfere with the radar altimeters that airplane pilots rely on to land safely. Not true, said AT&T and Verizon, with the backing of the U.S. Federal Communications Commission, which had authorized 5G. The altimeters are safe, they maintained. Air travelers didn’t know what to believe.

Another recent FCC decision had also created a controversy about public safety: okaying Wi-Fi devices in a 6-gigahertz frequency band long used by point-to-point microwave systems to carry safety-critical data. The microwave operators predicted that the Wi-Fi devices would disrupt their systems; the Wi-Fi interests insisted they would not. (As an attorney, I represented a microwave-industry group in the ensuing legal dispute.)
