A friend sent us this link from Gizmodo by Rosa Golijan on 2/1/11
He claims to have always called it "JIF". I however am old skol and still say "GIF" because that's what my professor called it back in 1990. Maybe I will change? Maybe not? DavidB says "GIF" and Cat says it both ways.
How about you?
Choosy programmers choose "gif" or "jif"?
