We’ve recently added comment feeds so that you can more easily keep track of comment threads posted on your (public) trips, using the tool of your choice (e.g. Reader, Bloglines or desktop RSS readers like Newsgator).
To access the feed, go to your ‘My Trips’ page (using the sidebar link) and you’ll find a blue feed icon and link to the feed, see screenshot below:
Use this link to subscribe to the feed in your reader of choice. Firefox or Safar render feeds pretty well too (see screenshot below), so you can alternatively just stick with the browser. The feed (Atom / RSS) contains all comments left on your public trip pages.
