The Long Tail - Wikipedia, the free encyclopedia

Ok, this is the most interesting concept discovered this week. Re-coined by Wired Magazine editor Chris Anderson, the long tail tells a long story about what's happening in business models, markets, and uncovers new market niches.

Still, the long-tail distribution could be applied to the language vocabulary, showing an ordenated set of decreasingly popular words. There would be one such ordenated set per language/dialect. The neat thing would then be, to compare a text word distribution with this language ordenated set, or compare distributions between languages. I believe it would evidence some sort of signature within a writer's work or within a language's identity.
