Journalists need to start making a stronger distinction between Tor end-use and hidden services. End-use is solid - hidden services are experimental. That said, the fact that this research can identify what hidden service a user accesses skirts that line. On the other hand, that doesn't sound too different from a typical timing attack (something that Tor doesn't try to prevent).
