I'm sorry Arch, but usually when someone offers a TalkOrigins article (which you didn't do what I'm about to say) it's always entirely short of what it promises to deliver but the sender demands that we go point by point through a 25 page dissertation of uncompelling rhetoric. It looks like Jason did the work for us to show the smokescreen.
Thanks, Jason.

He did? What part did I miss? It sounded to me more like Jason had dismissed Henke's work by calling it irrelevant. Never actually stated why it was.
From what I can gather Humphrey's did an experiment and got some results. Henke called those results into dispute (he didn't like Humphrey's methods) and Humphrey (to my knowledge) hasn't responded. I'm not sure what smokescreen you think has been blown away
I haven't found one article at TalkOrigins yet that doesn't completely falls short of it's title or is filled with anecdotal concepts and demands respect for them as sealed science.

I tend to try and avoid the larger articles there; they're just too long and complex for me to find the time for at present. But the smaller answers to creationists questions do (in my mind) debunk about 95% of all arguments I've heard.
By comparison I've read a couple of articles from AiG and felt sick afterward. The sheer number of outright lies that were present was disturbing. I've seen much better posts written here, with a vast amount more truth. Another article I've read didn't address the questions at all and just listed Biblical quotes.
On the other hand I've read one or two that weren't too bad. But I just can't trust anything from that site when I know at least some of their literature is completely false. To make matters worse it was
Arch, do you agree that the vacuum/pressure diffusion issue is a good sticking point? If so, it may be a good thread starter. It's news to me, so I'd like to learn the arguments. In the process we could all learn about the science of helium diffusion. Actually, we should move this conversation to the appropriate thread. Consider it done.

Apparently you are further in your reading of this subject than I am

I've no idea what the vacuum/pressure diffusion is.
Still haven't got around to reading those articles, I'll post again when I have

Regards,
Arch.
