well it still goes back to the original arguement that it has to be published and reproducible.
else it would be forgotten and re-discovered again at a later stage.
some scientific discoveries of the mordern era were actually discovered by earlier ancient people before mordern science started recording such discoveries.
The second, implied part, is that writing it down is for OTHER people to learn from.
So, although I hate the eletist gatekeeping language.. I think I agree more with the professional scientist than I do the professional clown.
