Purists are a good thing - it's what means the musical standards are high in any style.
That doesn't mean that you can't have a go and make mistakes, though! Play the music however you like playing it - the main thing is to have fun - if you tongue the notes even though this would be traditionally considered wrong - it doesn't matter! As long as you enjoy playing it, go right ahead. You only have to start to respect the rules when you want to play with other accomplished musicians in the same style. The music does become much more fun when you start to really play in the style though - a simple jig tune may be easily sight readable and simple to play, but it isn't a jig until you do all the other stuff that makes it sound so great - and that's when it's fun.
Play how you like - that's how you push boundaries!

I only have one and a half of above-mentioned instruments now, since the dog got hold of the bottom half of my recorder.

I like my penny whistle, but can't pretend to play it well. It sort of strikes me as the sort of thing that requires other musicians as well - it seems a bit lonely on its own. As for articulation - I don't know - but for me, it's like the piano in that 'if it sounds right, then do it that way' - methinks. There are probably standard, or 'easiest' ways of getting the right sound, but just look at Horowitz playing the piano! (Courtesy of Mad Tom on another thread.) Or, more importantly - listen. LISTEN is the most important word in playing any instrument.
You're absolutely right, when it comes to trad music, you can ONLY get it right by listening and learning - just playing from a score or using 'classical' technique because it's perceived as being right will get you nowhere - listen to the great players and learn to make sounds that sound the same and you're on the right track!
Agree one hundred percent!
