Sorry if I'm being dumb here, but why do you want them unstickified?
^^Probably because when there are too many stickies, it takes too much room up at the top which means that you have to scroll down further to get to the new stuff. So it may make sense to unsticky stuff that ended back in '07 when it's already '09.
Sorry, my fault! I've been overworked to the point that although I read and then replied 'unstickified', my brain was thinking 're-opening'.
