I just find it to be mean. If he said, "this rant is dumb", that would be fine. But all he said is "if you want to say something, make it shorter".
Maybe good advice, but you look like an idiot when everyone who reads social news site made it through Yegge's rant, but your couldn't bother reading your own employee's letter.
Really? I would have considered 'this rant is dumb' to be meaner than 'make it shorter'. 'Make it shorter' is, on the whole, pretty good advice for anyone who's trying to get their point across.
