Spent just a week in Hong Kong when I was 22/23 and got stopped for pictures 3/4 times. It felt like a real novelty at the time, but I imagine I'd tire of it eventually.
I grew up in a town about 80 kilometers north of London and used to go there pretty frequently, until I moved to Amsterdam last summer, so it was pretty surprising when I opened Facebook yesterday evening and was asked if I was safe from the fire in London.
I think Facebook's Safety Check is a good feature, but the implementation is pretty dreadful.
