iBeacon’s range is 50 meters (typical Bluetooth range), or 2,500 square meters.
That's some weird antenna right there. Assuming it's omnidirectional with a 50m range (radius) then it would cover more like 7,800 square meters.
The range of Estimote’s beacons is 50 meters, but the recommended range is 10 meters. If you go with the recommendation, you need 1 Estimote beacon for every 100 square meters.
I'm not sure it's a weird antenna. Looks like the author took 50^2 (square with edge length 50 m) instead of \pi 50^2 (the traditional interpretation of 50 m range).
Hmm, reading that after the estimote pages makes it seem that the gigaom post is just guerrilla marketing for estimote, that's trying to hijack the Apple publicity.
Have Apple actually stated anything public other than the word "iBeacon"?
Googling around I just find the same rewritten PR material all about estimote, not iBeacon specifically.

They discontinued the delicious import tool for some reason -- some technical reason from what I understand.
However, if you apply for an API key, there are scripts out there that can parse the delicious export and import into Evernote, including tags. Google for 'delicious export evernote script'.
I love 1984. I wouldn't say it was inspiring (its dystopian) but rather an eye-opening experience. It made me change the way I look at security and privacy.
If you liked 1984, then you might also like "We" by Yevgeny Zamyatin: http://en.wikipedia.org/wiki/We_(novel) (don't follow the link. copy-paste it with the (novel) part.)
I've never read 1984 (I hope to when I make time), but I understand that they are similar. In fact, I heard that "We" was the inspiration for 1984.
