I agree that this link to UC Berkeley takes you to a LOT of information. The site seems to be largely a site of links to other sites and does not seem to be too well-suited to aimless browsing. I suspect users need to have some sense of what you're looking for.
Having said that, however, browsing was not useless. Because so much information is accessible, I'd would simply need more time to follow to greater depth the interesting links that I encountered. Good resource for accessing lots of information through one source.
