I definitely think it would make the forums more interesting but it would also cause petty forum wars as well. I think the majority of the neg rep ive given out have been to people who knew they were going to get it. Their posting start out in all caps are nonsensical rants and tend to argue down people who show them proof they are wrong on something just because they cannot accept it. I think in all the neg rep ive given so far each of the threads have long since been shut down since it came down to the very bases name calling insults as well.
Id gladly leave a comment to some of the people as well, specially ones who demean belittle and insult those trying to help others. But there really is no need for me to if a person cannot tell by the - rep that what they are posting isnt constructive and is flame bait nothing I comment on will help or change that. But it would make for some popcorn popping times for sure.
I will even admit to neg repping the same person more then once. I felt the person deserved it and he does go out of his way to say stupid things in threads. He has insulted me on various occasions to so I feel free whenever he posts something irelevant or trolish to hit it only if its worth it to do so I do like to pos rep more and neg repping takes from that. But thats only one person and I never hit him for anything constructive only blatantly flame baiting posts. If I could leave a comment for him without it causing me infraction points youd better believe I would. Would it cause drama? probably because I feel he thrives off such things. Either way leaving comments wouldnt change it for as many people as you think not many of us go around just hitting the minus because we can not worth it in the long run as to me it takes away from being able to give out positive rep when its due.
