The Elvis Taxon & Taxonomy's Comeback?

Paleontology meets rock and roll: The Elvis Taxon. [via Kottke]

Maybe this is too soon to answer, but is taxonomy making a comeback? The term originally applied only to living organisms, but there are folks who will argue what constitutes or closely mimicks a living organism's behavior (social networks, information, perhaps anything that can be categorized).

Last year, Tortoise named a boxed set after A Lazarus Taxon, now we have the Elvis Taxon. With the increasing attention paid to user experience and information architecture, especially in terms of interactive media, I think we're going to see more references to taxa (plural of taxon) in general.
