Do karma point ever go negative? If they dont (which is my view) then the sum of comments is rounded to 0 if less than 0.

Karma = [SUM(KP1,KP2,..KPn) - n] + ROUND0[0.5x((KC1,KC2...KCm) - m)]

I changed ROUND to ROUND0 where ROUND0 always returns 0 or more. Is there a math way of representing that, that I cant remember?

This should be a philosophical question for Paul. Can the Karma be negative for a user? The trade-off then would be between absolute web democracy Vs keeping the users 'happy' (capitalistic?)

It's still absolute democracy there are just rules that have to be obeyed :-). Anyway the system is heavily (and rightly) skewed to encourage and award participation, hence no down-votes on submissions.
