First off I believe there is definitely a place for min-raising in a tourney as stacks get small in relation to blinds and any bigger raise would commit you too much. Also, I have actually heard pros (Ed Miller was one) advocate min-raising even in cash games. It's just that most of the time people do it they have no idea why they're doing it. Obviously it's a bad play most of the time.
Although I did hear, I think from BuckLox, that the way to determine who's going to win the hand is who wins the min-raise war, ie if it goes min bet, min-raise, min-raise, min-raise, min-raise, call, the last person to min-raise will most likely win the pot a good 90% of the time just because they won the psychological battle.
(last part obviously a joke, although it was in that video lol, first paragraph serious though)
