His site was indeed hacked recently, and it was harming my computer inasmuch as it was crashing firefox. I consider the google warning to be late but not incorrect.

Here's an email I sent to Joe on 2007-12-17. (It's really hard to make these kinds of messages not look like spam!)

----- Hey, I was checking out iui tonight, and your site seems broken.

The front page has JS that does something involving "fredkidns.com" and it repeatedly causes my firefox to fill memory. Kazehakase is able to show the broken page, though.

I think the blog top page is also hacked; other internal pages seem to be ok.
