Sure I'll join... ;-)
In my opinion, using a Map is one step below using a class with public fields (a.k.a. C-style struct). Both lose the advantage of encapsulation. However, a Map is worse still in that you also lose type definition (which fields are on a domain object) and type safety (which type is each field).
Yeah, I hate all that casting stuff you have to do in java when getting things out of collections. Generics thing in java 1.5 might help out with this.
