Buzz may not know that this thread exists... I know I don't always check all the new posts in all the forums.
I'd recommend making a short attention-getting reply-post to him in some other thread. That way he'll get an email that you replied to him and see that you're trying to talk to him. Your post will likely be off-topic, so it's best to keep it very short (and add a link to this thread where you want him to go).
But, I suppose sometimes people just ignore things they no longer want to discuss too... good luck.
Personally, I find your topic here interesting, but (like most of the biology-stuff) it's over my head so I don't feel like I could comment intelligently
