given that there's no standardized scale of usefulness, is the distinction between "useful" for one person vs "incredibly useful", when nothing concrete has been specified; is that distinction really the important thing here? both of you find it useful. I might go off on a long tangent about how I love my hammer, it's the best, and you'll think I'm ridiculous because it's just a hammer, but at the end of the day, we can both agree that the hammer is doing the job of driving in nails.
