I read an article recently by a web marketing advisor. He tried an experiment. He had some banner ads that needed to be done. He had the graphics guys do some, and then had some techie types do some.

Probably because they didn't sacrifice content and information for aesthetics...
The degree I'm currently working on is a fairly unique one in that it combines computer science with media/graphic arts. Which means I have to take design classes in addition to regular CS-type classes. There is a very clear disconnect between the two camps. The CS side wants the information to be presented clearly, cleanly and efficiently. The graphics arts value aesthetics far more than the message. Actually, they want the aesthetics to BE the message, even if the only way you can work that message out is if you have a degree in Fine Art, and even then you're more likely to completely miss the mark than not...
Very frustrating, sometimes, particularly when I design something that falls in line with some of the things we had been studying in user interface design (a CS class, though it delves into design a bit) and the media arts professor wants me to change it so that it is more aesthetically pleasing (to him anyway), but the interface becomes less easy to use...
