Are we speaking only of gaffes made by
professionals, or gaffes against
professionals as well?
A couple of years ago, I remarked on how the TOS Enterprise
is a timeless design that follows classic proportions while the Enterprise
-D is ugly and malproportioned. I suppose my tone was a bit condescending. Turned out I was replying to Andrew Probert, the guy who designed the Enterprise-D. (I wasn't paying particular attention to usernames.)
It was a bit like instructing Beethoven on how to write a symphony.
(BTW, I still think the Enterprise
-D is ugly.)
