Interesting enough... I'm just not sure of what "subliminal messages" I might want to be sending to myself. Also, there's always the possibility of someone hacking into your system and sending "un-wanted" messages. With them being subliminal you wouldn't even know the "rogue" suggestions were there until it was too late... for instance, until after you'd been fired from your job for lunching naked everyday, or commited to a mental hospital for clucking like a chicken at 4am everyday!!!
*OK so maybe I'm paranoid, but it's still possible!*
Don't know... perhaps that's because he's trying it out here first or something to see if it's going to make a profit or something with plans to expand to other markets later on???
