Here's what I ahve found as standard in 6max Nl10 and nl25:

Min-bet: Either nothing or a big hand, hopfully a cheap showdown will reveal which and you will know for the future

Min-raise: Almost ALWAYS bad news, big hand.

Edit: MY line with TPTK vs a min raise becomes call-down, for info and becuase your pot odds for improving to 2 pair or trips arn't that bad when someone is min raising. I'd fold if I alreayd had the info and was damn sure it meant i was beat.
