Meraki started using location aware adverts (indicating businesses
"less than a mile"), in San Fran. Their positioned at the bottom.
Interesting.

Unfortunately, they also "broadcast" your (geo)location, so it's
trivial to check visitors to your site, and know where they are (as
each access point is registered at Meraki). I can't think of a reason
for that information to be there...
