Stan, You wrote in part, > By the way, does anyone know: What is the speed of dark? Your question surprises me. The speed of dark is obviously 'minus 2,997,925 x 10 to the power of 8' m per second. Your points concerning chat responses were well made. My own view is that there is a place for 'chit-chat' type responses if they contribute to either: our knowledge of the list mood (ie short responses of the I agree/disagree type) or to our mental/emotional health in the form of humour. Every time a parkie grins, PD loses 5 hit points. A laugh = 10 hit points, A belly laugh = 20 hit pints. I know PD has more hit points than I can take from it, but its fun watching the dragon flinch.
