But you don't document the effort you put into telling people you exist. You've been the most prolific poster here for about thirty years now, and you mention other activities that make you visible.

We could and he did. Presumably you could give him something that the LeCroy module offered more cheaply than LeCroy did and without some of the bell and whistles that LeCroy threw in to appeal to a wider market.
