It's a silly question to want the answer to, though. You can tell someone everything they need to know to judge something on its merits, and they'll still ask whether it's "overhyped" or "underhyped", or, I suppose, "just the right amount of hyped."

Hype fluctuates over time and between different venues (e.g. right now Atom is being "hyped" on HN, but next month it might be the talk of /r/programming, etc.) Asking whether something is worth the hype requires the author to be aware of exactly the level of hype the reader has experienced, which requires, basically, being that individual reader.
