Anyway, the problem was that my script is (possibly excessively) paranoid about applying its comment-mangling mojo to anything that isn't a comments page, so it has an extra check that the url matches a comments page that it knows about before it does anything.
I fixed it by adding a pattern for community and syndicated feed pages (the url looks different than it does on the comment page of a regular user).
You'll have to install the script again, but that's as simple as clicking on the "this greasemonkey script" link above and saying "install". Greasemonkey overwrites scripts from the same source with the same name.
The problem with syndicated feeds and communities is fixed
That's what you get for being an early tester...
