A few people have said the blue is a give-away, can someone explain it to me? I use a lot of disparate systems at work, and the blue doesn't stand out - but I do use an ad-block to remove the ads and the OcUK logo at work.
I agree the decrease in +1 / agreed posts would IMO enhance the content of the forums.
I think they're suggesting their work mates or bosses can see quickly that they're reading the forums rather than working because the page stands out from a distance compared to other sites.
