The first occurrence of "troper" as a name for the people who record their thoughts on this site was in 2003, about a month after we launched. The term was coined by a guy who wrote a lot of good TV.
And a few movies.
The term has come to refer to anyone who enjoys examining, discussing, deconstructing, and lampshading Tropes. And as you are here reading this, this means You. That's right, You. Time Magazine's person of the year, 2006. Anybody who has a page here, and many people who don't. A "Vigilante Taxonomist." A person who gets it.
