Berlin is in Europe, so quoting the area as 10,000 m^2 (as in the original article) would have been nice. Are most HN readers really from the US?

Are most HN readers really from the US?

I ran a poll here a couple of months ago [0]. While far from being accurate, it could at least be considered somehow representative for the HN audience (it lasted more than 24h on the front page, so all time zones were covered). Even though the non-US group seems to have caught up compared to a couple of years back, the US still dominates the HN audience.

Circa 2009 (first Google result) non-US was 40%

I suspect most HN readers are from the US yes. Also, in the UK we're happy to use either feet or metres.

BACK OFF BRUSSLES! SAVE THE BRITISH FOOT! etc. etc. </sarcasm>

Or, to satisfy both crowds, the title could have had " ... 10,000 m^2 (107,000 ft^2) ... ".

[planetguy]

Or to satisfy both crowds it could have been either, and we could have assumed that the reader is smart enough to be able to know how many square feet there are in a square metre, to within the desired accuracy.

Ten and a bit square feet to the square metre. Know it, use it, love it.

Wow, that seems so obvious now! Never occurred to me before, but I love it.

[CurtHagenlocher]

Not only that, calling it "107,000 ft^2" amounts to inventing significant digits.

Yes, assuming this is broadly representative http://hackernewsers.com/pages/map.html
