This Greasemonkey script serves a similar purpose to the thread watching script but, in this case, it adds a button for adding the comments feed of a work to Google reader.

If you're a Firefox user, and you've installed Greasemonkey, and you're a RedBubble user, then install this:

redbubble-add-work-to-google-reader.user.js

After you've installed it you should find the button appears in the action list of each work.
