Hidden services are probably considerably less than 1% of the Tor network activity -- it's a way to hide chat or web services' geographical location, as might be used by the military to conceal command and control servers (one of the original purposes for which the US Naval Research Labs designed onion routing, the ancestor of Tor). Hidden services have never been able to be made highly secure or well performing, but Steven's research is still important and interesting. And Tor is not a project of EFF, although our URL is there, and they have been and continue to be great friends of the project. As of today we have become our own nonprofit.
