I can't say this enough, Tripit is going to change my world. Tripit is basically a travel organizing/planning site that you forward all those pesky emails that you get when booking air, hotel or car rental. It parses them and extracts relevant meta data. This is a productivity site for managing travel, the least fun part of actually traveling.
I am the designated family travel planner and spend hours and hours a year doing this stuff online. I just took 12 emails for 4 different trips coming up in the next 6 months and Tripit parsed them all and created amazing web pages for each one. This includes, hotel, cars, flights for 3 people with multiple destinations and non round-trip flights.
These guys are geniuses.
Just when I think the net can't do anything substantially new for me, something like this comes a long and I just go WOW.
Prior to tripit I (mostly) manually copied and pasted this stuff into Outlook, and then sent my wife meeting requests so she would have the info on her calendar. What a giant waste of time. No more...
Not to mention they integrate with sites like SeatGuru.com so you can get a good seat on your flight.
If this is the future, I love it.
