Assuming you're soliciting comments on the design...

A few things on the front page: What's the "Go to next page" for? There are links all over the page, what could "next" page possibly mean?

What's the text box on the left? If I type random text into it and hit return, I get two error messages to the effect that I'm STOOPID because I did something WRONG. It appears that what was expected was an email address, but the text around it doesn't suggest that very well. And second most prominent thing on the front page is not the place to put a sign-up for a mailing list.

"Singularity Institute produces breakthrough research on emerging technologies." That (a) needs a "the", and (b) communicates nothing. The mission statement on the "next" page says only "the Singularity Institute exists to ensure that the creation of smarter-than-human intelligence benefits society" and a bunch more links. This is making a lot of work for the reader trying to find out what you actually do. The "research summary" link goes to a paper that is not a research summary.
