In his latest blog Seth Godin riffed on about things being stuck, citing the airline safety procedures.

We have 100% seatbelt understanding among the flying population ... why do flight attendants repeat the instructions literally millions of times a year? (Low and flat across the waist ...)

It might not be that the airlines are responsible, it might be the FAA stipulating that this must be done. There's no doubt that many things are stuck, and it's important to know where the ‘stuckiness’ is if we're to fix the problem.
