9½ years...slow & steady.

The way I'd determine the 'answer' is to make a list of "names I remember immediately when I see them and have a good idea of who they are, how they think and what their interests are."

There must be a couple hundred of those, even if there are days or weeks between posts.....and I suppose I am 'aware' of 500 or more names that ring a bell when I see them....(oh, this includes those nice folks ABOVE the line...*grin*)
