In case it's not obvious:  links to a chan style discussion board, with chan style culture. The first thing I read (because it's in big red letters) was "I WANT TO REMIND YOU THAT CP IS NOT TOLERATED AND MUST BE REPORTED".
Sorry, possibly could have made that more clear (it's also not affiliated with Gentoo). In defense of 4chan, the exact same rule applies to HN (the law applies to everyone), every large website has trouble with spam, and there's nothing offensive there outside of mild profanity and teenagerism.
It's otherwise a perfectly ordinary technical discussion thread from a board that has a large number of firefox users and where Nightly is strongly encouraged amongst PC enthusiasts.
