Just in case my previous post didn't come off tongue and cheek enough, I have to completely agree with DFNYC, Janskeet. Your thread had no context to it, so it should be no surprise that none of us knew what you were talking about.
DFNYC is right that you cannot assume that every member keeps up with every active thread. It is not a bad idea to make a new thread to talk about something touched on in another thread, so as to avoid hijacking the original thread. A good way to overcome the issue of context, is to take a few quotes from the original thread to set the context.
