Defining the long tail

Chris Anderson posts reader-submitted definitions of the term "The Long Tail".

I particularly liked Eric Akawie's contribution:

The Long Tail is what you get when the obscure becomes ubiquitous.

Another of the submissions -- "An embarrassment of niches" (by kpk) -- reminds me of an amusing story from a while back.

Jeff Bezos, during a presentation to hundreds of people, showed his Amazon.com recommendations. His top recommendation was the DVD "Slave Girls from Beyond Infinity".

Turns out he had just bought the DVD of "Barbarella", so the recommendation was fairly accurate. But still an embarrassment of niches.
