This week, after a dinner conversation with Stowe Boyd, I’ve been adding new features to our Atom feeds.
From your Account page, you’ll now find a link to a feed that just contains your trips (optionally with past trips included too). Why would you want this? Because the feed contains a lot of machine-readable information. Here are some ways to use it:
Put your itinerary on your blog sidebar
Most modern blog systems will take an Atom feed URL and import the entries as a sidebar on your blog:

Map it in Google Maps
Google Maps understands the GeoRSS entries in the feed. Here’s all the trips I’ve shared since Dopplr began in early 2007:

Export from NetNewsWire to iCal
Just like the main Dopplr site, the new feed uses the hCalendar microformat which some feedreaders can use to import trip details into calendar software. Here’s a screenshot of NetNewsWire importing a trip into Apple iCal:

Use your Javascript, your Yahoo Pipes and your imagination
The examples above are just a few suggestions I came up with this afternoon, and I didn’t even mention the Google Data-compatible event data. With a bit of extra work, I’m sure you’ll come up with something much more interesting.
Remember that the URL for your trip feed is personal to you - it’s got a code on it that no one will be able to guess. So think carefully if you’re going to embed that URL in a public widget (like I’ve done with mine in the Google Map above). Once someone has the URL, they’ll be able to follow your trips through that feed, even if they’re not a Dopplr member. Personally I don’t mind if my trips are visible in public, but you might feel differently. Code carefully.
