Here I thought Flickr didn’t use the ‘e’ in Flicker because they wanted to be unique and interesting. Instead, it turns out whoever owned the domain flicker.com didn’t want to sell it so the Flickr founders just dropped it.

Unwittingly, they (and this person) started a Web 2.0 trend that still continues. Droplr, Tumblr, and others. Coincidently, I own a few domains that have that only have the ‘r’ instead of ‘er’ in it’s name. (I’ll sell them, though.)
