Carbon seatpost - replace if scratched??

[Flur]

I felt so bad for the TdF rider whose carbon seatpost snapped in Paris. The cameras showed him for several seconds, and I sighed with relief when he kind of "sat" on his top tube. (all I could think was "ouch! get off that bike!")

I saw that too. That's what made me worried I about my seatpost scratches! I don't come out of my seat much when I ride, so if mine snapped I'd surely wind up falling onto the back wheel, or worse.
