You asked for it...
I'm from Berlin and just discovered geo hashing recently.
A friend told me about this TV show she likes called 'The IT crowd'. Having never heard of it I visited ever-so-useful wikipedia. And there, somewhere within the article, I stumble upon four blue letters... xkcd... which take me to the corrisponding article and the relating website. And some days (and lots of laughter) later here I am...
 Been there, done that
Do they exist to be used for showing off?
Gaea's blessing for all the fellow hashers out there!
I'm going to visit my birthday hash when this years spring sun shines warm and bright upon it... 1986-06-04_52_13
