And I've been around twice as long as you! I also understand the reasons for the humor taboo.
But there's a sadness about the Yahoo situation that invites joking as a coping mechanism. If we don't laugh, we'll have to cry. Or rant.
And speaking of rants: plenty of upvoted, 'serious' comments about this incident are just variants of "HUH-hah, look at Yahoo's latest screwup!" Those can be even worse for reasoned discourse than a few silly quips in one tangent. But HN smiles upon the hyper-critical and mock-aghast sort of rhetorical competition.
