It looks like I failed to convey what I've tried to say in the first comment. Let me reiterate one more time.

    - I believe dang sees HN as his baby, so *voluntarily* monitors it as a critical infrastructure *for him*.
    - I personally like this kind of commitment from people who like their job, however *I don't expect or demand it in any way*.
    - I also hope that attention doesn't affect his life. *Especially negatively and/or in a crippling way*.

I also keep servers up in my daily job, and some are more important than others, but none of them requires me to wake up 5AM to solve a problem (by design). So I don't demand anything from others something which I won't do.

As long as nobody is dying, nobody should stop, drop, and work on something else regardless of time, date and location.
