I've long raved about the merits of Tripit for those of us who travel frequently. It's indispensable for keeping track of flights, hotels, car rentals -- everything, basically. (And it's available in free or paid form, which is a plus.) But until now it's only really kept track of upcoming trips. And that's certainly the most important thing to keep track of. But there are plenty of times when I'd like to look back on past trips and know where I stayed and how I got there.
Tripit's taken care of that in its latest update. You can now see past trips and all of the attached itineraries. So if you stayed in a great hotel but can't remember the name, you don't have have sort through e-mails. Or maybe you want to give kudos for a particularly good flight. (Or maybe you just can't remember what city your were in. It happens.)
Me? I'm totally going to use it for bragging rights. But hopefully your use will be a little more humble.
