I must say, between Jeff's first post on this argument and another discussion I saw this morning here on HN I got a bit paranoid and just now finished changing _all_ of my passwords, each generated and stored using an automated tool. I acted on impulse, and yet I don't think I'll regret it, even if it was probably overkill. I "fortunately" lost just two accounts too, among which there was my "old" HN one.
