You do have a point and I was aware of that unfortunate side-effect of my comment. I'm doing it rarely. But this is also a site for people who make decisions on how stuff is published on the web and how to monetize it, etc. So I think it's not completely useless to have that kind of meta debate sometimes.
The worst thing about Scribd is the way it obligates people to ruin perfectly good HN threads with meta-commentary.
