Lets do it to it capt'n.
The "sit and watch and burn" aspect of your analogy doesn't really work with a hockey board because I don't think anything negative comes from not posting due to volume. Again I think that most people don't post because when they go to post, they've read 4-5 pages of a topic and see that most of what they want to say has been covered. I don't know if most people are getting a "burn" so to speak, as much as they are just opting to spend their time elsewhere.
As for the "cooks" statement. Yeah, didn't think it through that much
. I was going for that fact that if most of us keep on going on about the same thing (adding more and more salt) its going to make the topic less interesting for others (bitter taste) as everything is going to be re-read for the most part.
