I also noticed, just yesterday, that there is a link to a Firefox plug-in for searching HN. The point is I only noticed it yesterday and I've been on HN over a year - same with searchyc - i didn't really know about it until I got fed up with not being able to searchyc and started googling for it. If people at HN are so bothered by dupe submissions then a search on HN should be run by the system at the point I submit a link. I shouldn't have to think about it otherwise.
