Both The Register and the BBC have stories today on bluejacking – that is, the practice of sending unsolicited messages to open Bluetooth relay points, typically mobile phones. There’s even a web site dedicated to bluejacking.

One of my personal favourites is the cinema. It’s fun to fire off pictures of fridge magnet letters with my web site URL, or note text, to random people as they come in to the cinema or as they turn their phones on and leave. Lectures, too: had a bluejack-chat with somebody a little while back. As always, us geeks are well ahead of the technological fashion trends.

I’ve gotten no work at all done so far today. Hmm.
