Bus14,
Ray lost the argument some years before he began it, so that's not an issue
The main points about Bluecoat and my participation are
* I spend much of my time thinking about and discussing accidents. That is a no-no on bluecoat.
* BB's participation philosophy includes careful control of discussion, and that was my real problem. My experience with technical on-line discussion groups, which extends over some 25 years now, is that they are fragile things whose worth is equally shared between the contributions of its "top" members and the occasional decisive intervention by chatterers. So I am not much into control of discussion because one loses the second of those factors.
* I am a bit out of touch now with people and developments in avionics (John Rushby, Paul Miner, Kevin Driscoll and co) and more in touch with rail and automobile people. The problems commercial aviation had, mildly, with digital avionics two decades ago are now beginning in spades with cars, but they are not the same issues. It turns out to be hard to specialise in both.
But I'll think about it.
