[Edit: As pointed out by logn, the parent comment is actually a link to a different but realted post, even though it came across otherwise. Leaving the below for context.]

Things often are. That doesn't mean everyone here has seen it, or that it isn't still interesting - especially in this case when it was posted nearly three years ago.

It can still be valuable to look at the past discussion. People who post a link to the old one aren't being mean, they're letting people know that they can look back at what others have already said.

Note too this article is about the making the second version of the sound just released (http://www.thx.com/consumer/movies/120832135). Also he clears up a myth he started about the original code being 20K lines.

I also agree with joshuapants sibling comment and appreciate the context.
