Noise is in the eye of the beholder. It seems a little self-serving and belittling to humanity to care about the message more than the messenger.
If I point something out and you comment, it's simple common politeness to allow you to drift off topic for a sentence or so. To care more about noise-to-signal ratio than a simple plug is to take humans out of the mix and turn boards into simple data.
I exaggerate my point for effect, but it still doesn't sit right with me. We're more that data machines for discussion boards.
I see it as noise because it's redundant. All posts have a name and a profile associated with them.
Personally, I think you have to earn a reference to your personal or business site. And you can do that by saying interesting things, which makes me curious to find out who you are by clicking your name. Which, again, I often do here.
