Obviously the average user is "well trained"

Has the entire population of the planet been turned into some sort of pavlovian dog? The merest hint of an e-card and they are merrily clicking away (and probably wondering where dinner is)...

I am put in mind of those pigeon guided missiles where the hapless bird is taught to peck in a certain place (thus guiding a missile) until they hit their target.

Perhaps we've discovered a new use for gullible fools?
