I believe that there was a post about this before.

IIRC, the way that HN is set up, it re-distributes the "fnid=NSgN9i46gR" parameters at the end of the string to the first/second/third/etc. pages.

Reddit (a similar example) does this, but it also does it in such a way that the parameters "?count=50&after=t3_ihoin" fit into a SQL(/alternative DB) select statement.

This would probably be a better way for HN to do it, but they probably have a reason for why it's currently done this way .
