A lot of buzz about Node shouldn't be confused with a lot of "hype". If people are talking about something a lot and using it for very specific projects that's very different from people evangelizing it as a silver bullet solution for everything.
A lot of buzz can qualify has "hype" in my opinion. Node has gotten a lot of attention over the past year, just like Erlang got a few years before and Haskell in there too. The only difference people actually started using Node.
