I used to use a web browser with Emacs keybindings, so visiting a URL was the same keystroke as opening a file. I'd type "C-x C-f news.ycombinator.com" quite regularly, and my fingers still go to that "n" when I visit a file in Emacs.
LOL, same. In fact, every site I visit often is one char + enter in the browser. With the exception of W, being east of the Mississippi every station starts with W.
That got me to thinking about 'first letter advantages.' If a site has a first letter not currently in use, I'm much more likely to visit it more often(mostly out of boredom, sure).
V and X are still available if anyone is wondering. Zillow got Z!
