If you already have a machine serving stuff at home, adding a remote server is only time, money, and effort spent. Is it worth it? Not all sites are high in volume, and even well prepared sites on decent lines can go down if it hits the HN front page.
People do occasionally bitch and moan about slow downloads from my home host, but nobody ever offered money for a pain-free alternative.
Well it is the main reference but it won't sustain the "HN effect", thanks for the mirror link. I typically use http://wiki.bash-hackers.org/doku.php which also provides a mirror and some extras.
