Earlier this week, I was invited to give an talk on image processing techniques to a small group of senior-level engineers who work in a "certain sector". When I opened up the floor for questions, one audience member immediately shot a question at me. I shushed him, and whispered, "Not here man. Reach me on #Signal." The small room erupted.
OK, that was not at all original and a low-blow at best. But that still gave me a certain amount of satisfaction.
Such little #digs are good for this underdog's soul. The underpaid archaeologists might well be the most contented people.
