To be honest, I don't think they're a good idea.

In my first two animations I put in huge credit sequences. Both 2003 & 2004's submissions had credits ~1:30secs, thats just flat out silly.
This year I came to a realization: Since the animation is so short, credits are not needed at all.
Heres my reasoning:
1) There are very few people involved. Usually its less than 5 people, and in most cases there are only 1 or 2 animators.
2)You're not using that many outside resources. Most of the content for your animation you made it your self, or its from the 3ds max library.
3)Finally: Thinking logically, when someone is judging your animation, you want the last thing in their head to be, your animation. Adding long credits takes away from your hard work. Think about it. o.0
Basically, if you want to give credit to the creator(s) just slap it on the title slide. Why not use those free 6-seconds to the fullest? ^_^-b
