It's about engaging and entertaining people. That's where things can become dated.
OMG - everyone at the magic club I occasionally go to seems to be stuck in the school of lets do all of Tommy Cooper's and Paul Daniels' jokes - argh!!!
Regards the googling.
I never name the trick, not for this reason, but because it's not necessary
"I'll now show you a trick called ... " - who cares?
I know a guy who does this on every trick, and it's blatently amateurish, longwinded and boring.
If someone told me they were going to google a trick, I would say,
"Ok, if you want to, good luck with that." - I imagine it happens so rarely to become a problem.
My magic is about engaging people on a level that goes beyond tricks and puzzles, so I'm hoping for 99% of people it's not even going to cross their mind to research how to work it out. Yes, some people ask 'how did you do that?' but most of the time they don't actually want to know, they are just asking because they feel they have to say something.
my answer is always, 'did you enjoy it?'
they say, 'yes'
I say, 'thank you' and then we carry on as if they never even asked it.
