Was thinking about it, and I don't think I have arguments that would convince you :P But if we happened to work together and you were ignoring my pings long enough but was responsive to i.e. well written detailed emails, I think I would adjust.
But for me, ping signifies "I think I need to talk to you, but the details are kinda sketchy, so get back to me at your confinience.".
