"For code search, that means it can do things like show you how other people actually call a given function."

i just tried it and that is a pretty big claim.

e.g. https://sourcegraph.com/code.google.com/p/go/symbols/go/code...

Am i wrong or isn't this pretty much what Intellij calls "Usage"? At least I don't see the difference, could you please explain it?

general feedback: the website is too slow. it takes me a couple of seconds to load each page, rendering the page pretty much useless.
