I'm sure I wouldn't want to find myself at the other end of a Theo or Linus rant, but they sure are entertaining to read. Let's face it: a majority of people probably wish they could be so direct, especially when dealing with those who do effectively zero research before wasting everyone's time.

I'm not sure the majority of people really wish that. There are plenty of places where you can rant on mailing lists, but it's not really a great way to spend time. Better to just calmly correct things that are worth correcting, ignore things not worth responding to, and move on to other things. Imo this style of rant isn't even entertaining once you've seen more than a few of them, because they basically follow a template. (Suggested AI class project: write a generator for Theo rants.)
