"Ah ok. I looked at it more as something you force on your co-workers :)"
Looks like 'ah' implies negativity to the algorithms driving this.
Edit: It's also only pulling your 50 most recent comments by default. That covers about the last two weeks for me and is probably why it isn't very accurate. 50 comments is a very small dataset to work from. The other option it gives is 50 oldest comments - again not very representative for someone who has been commenting regularly for 1301 days. I try to keep my comments useful but I know for a fact I've gotten into emotional debates in the last 4 years in which I was negative/stupid/hating. Maybe it's not possible but I would suggest pulling a random sample of 100-200 comments for more accurate data.
