Here are some newish travel sites you should know about:

TripIt.com: A terrific site that has changed my travel life. Instead of printing out separate e-mails for my hotels, flight info and meetings, I have one document where it's all combined, broken up by time, etc. In most cases, I am able to send my booking info to plans@tripit.com and it automatically puts all the info in the right places (this works only from the major booking sites, but is pretty cool). I am also able to easily share my travel info with family and friends.

Dopplr.com: Sounds like a weather site, but is a travel site aimed at frequent business travelers. Jimmy Wales, the founder of Wikipedia has called Dopplr his "favorite non-wiki website." He said: "You put in your travel schedule and link to your friends. It allows you to see where everyone is. I love it."

A collection of Web 2.0 travel tools: Check out a range of sites you have probably not seen yet.
