I'd like to think pilots of all experience levels know what is and isn't a good idea and what they are actually capable of. I've seen threads about flying on water, the infamous impossible turn, taking off with maximum flap set and also TV shows about landing on frozen lakes or dunking the wheels in the water to slow down to land on a river bank. To be honest I wouldn't personally try any of this with my curent experience level.
I have flown with an instructor that thought it would be fun to fly at -10 feet (altimeter) over the sea, who was also the type to wheelie it down the runway, only banging the tail on the odd occasion, and I haven't emulated any of this either.
I think it is fine to discuss these things on a public forum, and I don't think the more experienced guys should feel responsible for what a nugget or scrub will do with that information. You have to be responsible for yourself in life, and this becomes even more important when you are a pilot as flying affects more than just yourself.
