Over yonder on his blog, Bruce Sterling says,
I've been noticing that successful tech neologisms tend to have children. For instance, the term "AJAX" was a little suspect at first, because the acronym for "Asynchronous Java and Xtml" doesn't always entirely jibe with programmers' actual usage of web techniques that get called "Ajax." However, Ajax spawned "COMET" and "FLORWAX." This lineage makes Ajax much harder to kill.
"Folksonomy" has now reached a similar fertile-adult stage with the coinage of "personomy."
