Answer 1

I agree with some of the other responses here that it is the classic singleton which maintains a single instance of a stateful object which is to be avoided and not necessarily utility classes with no state that are evil. I also agree with Reed, that if at all possible, put these utility methods in a class where it makes sense to do so and where one would logically suspect such methods would reside. I would add, that often these static utility methods might be good candidates for extension methods.
