The Tutorials section is now fairly well maintained by an active committee, so the problem your script attempts to help resolve has been pretty well resolved. And I should point out that linking meditations nodes into Tutorials is a matter of resolved policy (though it could change), so it doesn't do us any good to tell us we have meditations linked in Tutorials.

The only foreseeable need for your script will be when (if) we go back and convert all the crappy unlisted tutorial nodes into something else (probably Meditations).
