All I can see here is people moaning because this isn't what they have come to expect from HN. It isn't a startup? Not a new Node library? Omg, this isn't some hip news? It shouldn't be in hacker news!
Someone just transferred ~100 million dollars across the net without a bank being involved. Even without knowing anything about why or who, just the fact that this occurred is interesting. Money is one of the earliest information technologies and bitcoin, whether or not you think it will be successful in the long run, is something that anyone who professes an interest in technologies should be watching very closely.
No, I expect it in the page. (And presumably, so did they.) A link to a large bitcoin transaction with no explanation tells me nothing.
