This was mentioned as a concern when Steve Jobs died:that budding ninja technologists would try to emulate his puportedly nasty management style.
Fortunately, I think this sort of nastiness is self-limiting. The only really egotistical, nasty rock star I ever worked with destroyed himself, much to the delight ( and with some assistance from) his colleagues. I think that would be be a far more likely outcome than a nasty rock star continuing their ascent with a bad attitude.
Linus may be an ass at times but he has earned that right, and is one of the few people from whom an abrasive attitude is tolerated. I would strongly caution you that most people do not find that sort of attitude acceptable.
And yes, this is a throwaway account. It might be worth considering why I created it to respond to you, just based on your post above.
Emulate Linus' style in commit messages if you wish.
Don't emulate the abrasiveness in his style of communicating (unless you have a track record as good as his).
