I sat through an interesting talk during which the speaker (this was from months ago, don't recall the speaker's name sorry) brought up Kramer from Seinfeld. In this one episode, Kramer spills coffee on himself (http://www.youtube.com/watch?v=TysjNDTWEBc) and sues the coffee corp. During the negotiations with the corp., Kramer sidesteps his lawyer and accepts the first deal the corp offers (free coffee for life) without careful deliberation.
Moral of the story: he could've made a handsome sum, but instead he spoke too early. Arguably, you shouldn't follow Kramer's approach to a sellout or a buyout, etc. What the title has to do with this story is that sometimes it's ok to be silent in order to observe the nature of the course of a conversation or a comments thread.
There seems to be too much chatter about HN quality lately, which by itself is fine. But, it's the petty ones (though Karmically balanced) that reminded me of this author's closing words about personal relationships that could be applied to the HN comments section - "If it doesn't make that much of a difference to you, please don't say anything."
