I didn't mean to address particular annoyance at the poster. If annoyance is merited (I'm no longer sure, but based just on the concept/precept of having a "unique" or canonical-shared identifier for content, I'm troubled), then it would be at Blogspot for creating this circumstance.
If blogspot hadn't tried to localise me, I'd have submitted a .com link and HN would have spotted that this story is actually a dupe and we wouldn't be pondering this topic all over again .... :)
