A good example -- google voice announced months ago (when the site launched) that portability would be coming soon. Somehow Arrington figured it out yesterday and posted a really poor story implying it was some sort of "secret" weapon for Google (and got into the requisite argument with a commenter). That story somehow ends up on the HN front page.
I don't get the HN obsession with TC -- slashdot / reddit / digg and the other nerdy sites seem to ignore it and I wish this site would treat it like what it is as well.
