I think it's more of an intimidation factor, those of us that are new feel less inclined to share opinions with those who've been doing it far longer than we. Nobody likes the rookie coming in and telling the veterans how to do something or that something is crap (which it isn't btw, I esp like the first). When I see one of the colored names I immediately think, oh this guy knows what he's doing so I'll just keep quiet until it's done...then I'll sing glorious praises. And I know how ya feel, kinda, not many comments on my fjord so I'm thinking it either totally blows or totally blows minds...I always think the former but press on diligently anyway knowing I enjoyed the effort.

Anywho, my 2 cents
