And I'm the orange guy you were replying to. As I replied later in the thread... please ignore my oranginess. I don't like it either. I think it's a mistake. You want good comments to rise to the top, not assume that only people who've made good comments in the past are the people to listen to.
I might have only BS to say on a particular topic, yet get flagged orange because I've said interesting things about other topics.
Happily, it appears that with my setup (vista on high contrast black theme and FF3) everybody's just blue. Not that I think I'd actually care if they were different colours; I suspect quite a few of us on here have the personality trait / social dysfunction / whatever of not giving a flying fsck about externally determined rank, and being much more interested in whether a person has earned -our- respect directly.
