It feels strange that i should have written about the radio just a few days ago.
now, one more thought related to radio..
i was at a user conference in the silicon valley area.
this area has always been very high in terms of technology.
this time, i was impressed by a technology called nTAG.
a device that was given to every participant, it could recognize other participants, detect your presence in a particular session, enable exchange of calling card information, participate in live polls, surveys etc and also manage one's schedule of visiting various sessions.
all this over RF technology.
the scary though is: someone can and probably is - constantly watching you, as you move around, meet with others etc.
