I know 2016 blocks is roughly two weeks, but why did satoshi chose this connection of the protocol to the 'real' world?
I mean, for me it would make some sense to make it sync with the block reward period which is 210000 blocks.
2016 is not a factor of 210000.

Was this done deliberately? Yes, of course it was, but why?
Was this number chosen as some sort of 1337 hint to this 2016 election year?

Why did Satoshi not sync this to the block reward period and use 2000 or 2100 blocks(which are both a factor of 210000), which 2000 as most obvious round number.

Since bitcoin is a global internet phenonemon it doesn't make sense to me to sync the difficulty adjustment with 2 earthly weeks.

Personally I stick with the 1337 explanation until I see another reasonable explanation.
