I never followed the Knox case, but I now looked at some of the old lesswrong posts regarding it -- and at least one of the sites linked to (http://truejustice.org/ee/index.php), is currently down. As is the case with all broken links, this is bad for our collective memory of the arguments made and discussed back then.

In regards to this issue in particular, where we had "Knox test" by which people should look at the sides in question as argued by external sites, this is quite negative, if the sites go down and we haven't saved their arguments in question. (I encourage anyone who has cached versions of those sites to also save them in more permanent form)

I'll try to save as much as I can from sources like the wayback machine, but perhaps we here in LessWrong should collectively start considering ways in which we can make our old discussions less dependent on ephemeral external links. Too many links break.
