Once I was working for a consulting & development company; they were trying to enter sector ABC by stuffing up a team of people, so I was told, who had interest in sector ABC stuff and want to do some projects there.

While they were deep in software development in general, no body of them read any of the essential/required daily industrial news (also not that one related to doing software development in sector ABC)

:-)

So no, even people somehow attached to a topic are not necessarily somehow deeper involved.
