That's what spurred me to try LinkedIn when DHL messed me about - I'd had success getting issues solved when senior people happened to have their attention brought to my blog or whinin on Twitter, so I figured I'd try removing the middleman, at the cost of spending money instead. It was an interesting experience (especially as I got cc'd on some very interesting e-mails where people where told to fix my problem...). But that was a relatively easy situation that "just" required the attention of a couple of SVPs. Finding ways of drawing attention to more serious issues is a lot trickier.
I really believe that's true and wish it could be applied in more cases. Basically spread the problem to people who are normally not affected by it.
I would bet that TSA queues would get solved in ~2 months if all government workers and politicians (to the highest position) were excluded from TSA precheck and could not pay for priority queues.
