The work environment has changed profoundly since FreeBSD's beginnings. Most management is far less tolerant of employee "distraction" and far better able to track it. Academics had it better, but even that environment is tighter now. I've added a few observations to http://www.zefox.net/~fbsd/showstoppers and would be grateful if those closer to the project would correct any errors or serious omissions. My vantage point was relatively early, but also quite distant. Thanks for replying! bob prohaska > >
