If I may interject a voice of experience...
A single extended thread helps keep the "Oh my gosh, I had no idea, can you explain how this started ..." crowd posts down to a minimum.
I think new information should continue to be posted both on a single main thread, like this, and separately as new threads, for people who might not see it otherwise.
For people who have followed this outbreak from the beginning, a single combined thread is easier to track new and more accurate information with less extraneous comments.
That might cause readers of this thread only to miss some valuable responses on the other thread, but only if they're not paying attention.
Is the way I did it tonight, with genefromjersey's vanity thread, the way you're thinking of it?
