What's in a name?

I see the next task is for us to explore flickr. I already have some experience with Flickr, but I apparently am going to get more. I have to wonder about the name though. Did they name it "Flickr" instead of "Flicker" to save everyone an extra key stroke? Perhaps to save its users from carpal tunnel or to save time? Or is it to separate the users, those "in the know", from hopeless wanna-bes like all those girls in high school who wrote "I love Deaf Leopard" or "Arrowsmith rules" on the desks?
