I'm saddened to see the honorable name of Extropy and Extropianism, which carefully never descended to this level or anything like it, be stolen and captured by this nonsense.
And also, are you the real Eliezer?
"Extropy" is a term that was previously coined by a group of fairly nice people to describe themselves, and so far as I know is being stolen here without permission.
Seems like it was quite a time to be online. I mostly know of it through this version of events. Not sure how accurate you'd find it:

The word "extropy" itself seems to go back several decades before the mailing list, if I'm reading correctly here: https://en.wikipedia.org/wiki/Extropianism. Still, I wouldn't be surprised if many/most of the original mailing list members found this usage a corruption.
