Well, it looks like we have a dozen or so lurkers who made their first post...and there were another 6 or 8 replies whose names I'd seen before around here. So, maybe we have 20-25 lurkers? There's probably a few who didn't respond.
So, experiment complete.
As Brady says, "If anyone (and I know from long experience there are many lurking readers that chose to not participate with this collective) has a serious question, they can email me."
Long experience, eh? many lurkers? Empirical data would prove otherwise.
