These are trying times for magicians as we continue to struggle between education and exposure of magic. The line is truly fine - how does one justify oneself in either case? I'm not here to debate that issue, but it has seen the rise of a crowd of people who have become more savvy and wise to the art. One of the fundamental moves that have been under close scrutiny and under fire has been the ever venerable double lift. It's like an open secret now to laymen. A few of my magician friends have even gone so far as to swear off any effects that require its use, citing examples of how they have been called on its use by the ever 'witty' teenage upstart with a chip on his shoulder: closet magicians who are better at ruining tricks simply by existing than actually performing them. I can empathise with them - it's a tough crowd out there.
However, that simply means that we need to refine the methods and tools of our trade. We have to find ways and means to combat that ever increasing 'educated' crowd; being upset over it does nothing to solve the problem. Education works both ways - I believe while the crowd out there is being educated on how magic is done, we too, need to continue to further our education that differentiate the initiate from the master. Depth and breadth of knowledge are both equally important. We shouldn't discard a tool simply because it's weakness is exposure especially since it is a staple tool of the trade. We can deploy them in the best way possible through the understanding of the psychology of human behaviour and refinement of our own methods and skills.
I've found that convincers are especially effective in placating skeptical/semi-educated (in magic) audiences. By the time they realise that the move could have been used, they are too far gone to backtrack to it absolutely. Convincers allow us to put distance - either physical or temporal - between the method and the effect (read Designing Miracles by Darwin Ortiz if you have no idea what I'm talking about there... believe me it'll be the best $80 you spent in your magic career!). This makes for very strong magic indeed. ;P
