Someone in our marketing department was having trouble formatting something for the web and she came by to ask us for advice.  I happened to be in the room when they were talking and I gave my point of view that to save space in simpler images she should use PNG with custom palettes instead of jpegs.  She didn’t seem swayed and we went back and forth until finally a coworker burst out with “Mary, listen to the kid.  He may not have formal computer training but he has a blog”.  That is apparently a standard of some note and she departed without any more questions.
