You'd mentioned that your server was running out of memory, and it looks like the post-a-reply urls have changed, no longer exposing the id of the continuation.
How will you scale up HN for its exponential growth? Will the OS memory manager just page Scheme data structures out to disk? (Can you do a spam filtering for unhelpful comments yet?)
There has been an ongoing series of tweaks to deal with scaling. It's not planned, but I don't worry too much that I'll run out of room for tweaks, because the system started out so inefficient.
