As you can see, although it works perfectly at noisen.com, we want it to work both efficiently and as fast as possible in Wedge. While efficiency is not a problem in Noisen (nobody ever found my 'hidden' topic), query efficiency probably isn't. But because Noisen has less than a million posts, and far from that really, it's not (yet) a problem there...
