At a certain threshold of Karma (~500), A new HN user will receive the ability to Downvote. Athough per-user Karma is visible, it is so only for your own account and on a net-basis. Meanwhile, the reaction to other user's comments is only visible indirectly, via page rank. Having now a more than theoretical interest, I ask you for your Advice.
Ask HN:
What "Applied Philosophy" do you live by on Downvoting?
How do you use it?
How have you seen it being used? Against you or Others. Etc.
The end goal being a reference:
(1) Increase the data available to any given user from 1 experience (his own) to N experiences; and
(2) Articulate as appropriate best practices and/or debate areas of contention, etc.
Look forward to your thoughts.
I quickly learned that comments based solely on humor tend to fall flat and get downvoted.
Also, being overly negative and not offering something productive to the conversation will get you downvoted quickly.
Overall I've found the feedback of downvotes to be helpful and it's directly responsible for me raising the caliber of my comments rather than writing the funny responses that I initially think of. I tend now to just write them in the comment box, chuckle to myself, delete them, and then (try to) add something worthwhile to the conversation. Everyone wins!
