Ok, I know for the most part the forum rep system is considered a joke... I don't put too much stock into it...
However, I've seen too many newer players Neg Rep'd into oblivion for asking a "silly" question or voicing an opinion. Some deserve it, coming here to the forums and bashing the game because it is not like the "other" game.... Many do not.
I've also seen many posts of people complaining at how freely neg rep is given out, sometimes just because...
A simple thought came to me, It would be interesting to see how things would change if:
When giving out neg rep, you take a 50% of the value of that neg rep hit yourself....
This might just make people think twice before hitting that neg rep button because someone disagrees with you....
