It is a pretty popular web site with a part of the technical crowd. It gets analyzed a lot [1][2]. It also gets a lot of 'spam' (since coverage on the front page of HN can send you lots of traffic [3][4][5]) HN "scores" its participants using a counter 'karma' [6] which also affects features visible to your account (well at least the down vote button) And with any 'score' there are people who score more than others [7]. And where there is scoring there is competition.

The bottom line is that certain behaviors emerge for people who actively try to achieve a 'high score' (more karma) and people who are trying to achieve 'viriality'[8] (more exposure).

It was unkind of me to point out the behavior (usually I just note it and ignore it) and for that I apologize.

Colin (grandparent posting) has a 'thing' about stuff that gets doubly or triply or more posted. I understand the annoyance, it can get annoying. But I've also noted that he posts a lot of links :-) A number of people tend to complain when their version of the link doesn't make it to the front page when someone else's done (it's a 'I'm not getting that karma whine') And generally harmless (other than it sometimes back fires and they get down voted for whining)
