I wasn't discussing whether or not the post was funny. I don't care if it was funny.
I was reacting to what I think is an occasional problem with HN. In a nutshell, some people here take "serious" so far that it turns into "puritanically self-righteously lacking in any sense or awareness of humor or irony." That can lead to really bizzare misfires of communication.
Case in point is the reaction to a recent comment by Jrockway's on the anti-IRS nutcase: http://news.ycombinator.com/item?id=1135693 (again, please don't feel the need to say whether you find his comment funny or in poor taste or whatever).
I think the comment you link to is actually kinda an odd illustration of your point[1]: the first reply (Poe's rule) clearly recognizes it as humor and suggests that others will take it overly-seriously.
The second reply is somewhere in the middle -- at least it didn't start out with "OMG you are a terrible person how could you say that!!!11" I don't know who jrockway is: maybe he's making a joke, and maybe not. It's more likely that he's making a joke, but you never can tell on teh intarwebs... even in a place like HN.
Regardless, I wouldn't consider pw0ncakes' comment puritanical or self-righteous in the least: in fact he/she slightly revels in the possibility of fat-cat execs getting their comeuppance.
[1] Though I don't disagree with your point; I have indeed seen the issue of which you speak, though I can't think of any specific examples.
