I do not use Bluetooth, but a lot–a very lot–of people do. One recent estimate is as of 2008 there were at least one billion Bluetooth devices in the world, and I do not doubt that estimate at all.
I meet new people all the time. Not surprisingly, many of them are information security professionals. After we’ve said goodbye, I often look over their business cards a bit. What is amazing to me is the loftiness of the titles on so many business cards. I meet presidents, vice-presidents, CEOs, COOs, CTOs, CISOs, executive directors and managers, senior directors and managers, and by now you get my drift. But it does not end here–some have downright humorous titles such as “chief security visionary” or “I seldom see plain old everyday titles such as “member of the technical staff” or “security engineer.” Title inflation runs rampant.
