WTF as ligature
I’ve been a typeface-geek since the mid-80s when I’d wait for an hour for my dot-matrix epson to grind out a page of my homework in Palatino instead of it’s dotty default type. My favorite obsession is ligatures - those clever typesetting tricks that keep the f out of the i and give us interesting abbreviation characters like &. (see the Wikipedia entry for more info)
The crowd over at Typophile has been creating new ligatures for popular net acronyms like WTF, RTFM, LOL, et cetera. (ligature of WTF shown by Mark Simonson)
