Thanks! I should note HN is not a big source for us but due to the time lag involved with weekly publication (about 50% is e-mailed in), a lot of stuff ends up on HN more quickly.
That said, I see at least one item a week that hits HN an hour or two after us, and occasionally stuff that even hits HN months after we covered it ;-) So it's swings and roundabouts.
It only takes one reader to agree with you that something is interesting for it to end up on HN after all :-)
I wouldn't worry about that -- most of the really interesting (hacking/programming) stuff on HN isn't time sensitive. A tutorial/intro on <lang/stack/arch/design> that's great today, will be great in a year as well.
