Comment 9 for bug 72815

Well I read https://help.launchpad.net/KarmaReductionJan07 and there's a note that says:

  Everybody's Launchpad karma decays slightly over time, to reflect how recent your work has been.

Most of us answering the posted questions are volunteers and as such we do it only when time permits. Karma points are our only incentive so if one is so busy when he logs in back he'd find his karma reduced! As if he hasn't contributed anything.

To reflect how recent ones work is, one should use time/date instead and leave karma points alone.
