Back in October 2004 I received the following note on a workshop evaluation:
One distractor [sic] was that the presenter referred to a .gif file as a .jif file. There are folks that rabidly insist that .gif be pronounced the same as .jif but that confuses the two file types when spoken that way. Common usage (and common sense) dictate that .gif be pronounced with the hard g sound to avoid confusion the the .jif file type. Like I said, it was a major distractor [sic] to me. It also pointed to a lack of basic understanding in an area where the instructor is supposed to be presenting correct information to others. It makes a person wonder what other bad habits he might be perpetuating.
Head on over to the original post to see what I had to say in response.
