I've had people ask me why I always refer to it as "the facebook" and its fun explaining to people that that really was what it was called at the time I signed up. Also, "the facebook" was late to my college campus (relatively) so we hopped through a small collection of facebooks. It's weird today that most people don't realize there were multiple competitive facebooks or that it was essentially a generic term before it was a brand...

It's especially weird when I see people roll their eyes or laugh at someone say my grandmother's age referring to it as "the facebook", because to them its quaint and elderly, and I'm tempted to break out the "get off my lawn, that's what it has always been called" speech... Internet history is weird.
