Cool, but it doesn't take retweets, @replies, and quoted replies into account. My worst comments over on Reddit are where I quote someone else who said something mean, and the same goes for Twitter.

And the results for HN are truly head-scratching. Use of the word "fucking" regardless of context is apparently enough to elevate a comment to "worst" status. (Watch me get a few points just for this comment alone!)

Don't get me wrong, this is a neat tool, but it's going to be misused in character assassinations on others, especially with its current presentation, where phrases are used like "troll score", "most insulting" and so on.

I'd really suggest toning that presentation down and emphasizing the fact that this is imperfect until the algorithm has been tweaked further.
