Well then, in the same way, putting "Abstract" in front of a class that is abstract is equally meaningless. My IDE shows me that too!!

I disagree. Putting an "I" in front of something that is declared as an "interface" already is redundant. My IDEs (I juggle between Eclipse and IDEA) both easily show me what kind of beast a particular reference is if I want to know. In most cases its irrelevant whether you're dealing with one or the other. Tapestry is the exception here - no other API I work with uses this old-school Hungarian notation. It's not really worth dwelling on, though. Howard has already agreed that moving forward the I-prefix will be dropped for new code. The question now is what to do about the existing interfaces. Putting a cleaner name in interface hierarchy (RequestCycle extends IRequestCycle, or vice versa) and deprecating the I-prefixed stuff seems to make sense. This will be ugly though - as method signatures using those interfaces will need to be duplicated with the old one deprecated - right?
