If you travel and haven’t yet heard of TripIt, you’re going to be sooo excited! TripIt is a site that keeps track of your travel. But unlike many other sites that promise to help you with your travel, this one is so easy and useful, you’ll actually use it.
Here’s what you do: when you get an itinerary from the airline or a hotel, just email it to email@example.com. You’re done.
I found this really intriguing — this sounds like something that could actually be really useful. Sadly, it couldn’t handle any of the five test flight bookings I sent to it, somewhat unsurprising as they were coming from European airlines. But there are probably many more cool ideas one could build using an email interface.
