That is absoulutely FUBAR. I have not seen anything like that to date, nor heard of it.
One thing I see is that the cache version of these pages are unavailable. It pops up that message on all of your pages.
It could be your character encoding. This is the first time that I have seen encoding strictly for the Mac:
Code:
<meta http-equiv="content-type" content="text/html;charset=macintosh">
It just may be, and I am only guessing, that Yahoo cannot read it correctly or it cannot display it correctly. Again, I am only taking a wild stab at this.
I did look at your pages with the text browser (Lynx) and they quite readable.
As for the pages not getting indexed (as much as Google does), welcome to the club. You are in the same boat as the rest of us.
