The link is great but how many times it was posted here ?
I would like to propose for a solution to this. To avoid reposts, why doesn't HN create a "Sticky" of good resources like these? It would definitely reduce reposts and also act as a "Go to" link for X(Technology/Tool/Books).
Everyday new people find out about HN and having a link where people can refer to for "typical HN" FAQ's would be great. Just my $0.02.
