I have to join the volley here.
One of my biggest pet peeves are websites that are one big image! This is where the designer simply created one image and used some software to slice and dice it into a website (usually using an automated tool).
The text is often smoothed, small and blurry...you can`t copy and paste any text...and the site takes forever to load. (since the images themselves are often far to large (in file size) for a website.
Unecessary Flash and autoplay music are above this on the list...but you`ve covered these thoroughly above.
(now let me frantically go through our site and make sure we aren`t on any of your pet peeve lists!!!! )
