gliider: handy web application that helps you plan for your next trip

According to the company's self-description:

gliider is a digital file that lets you hold on to all of the interesting stuff you come across when you're researching and planning a trip. Find a cool hotel you don't want to forget about? See a great restaurant you want to try? No matter what website you're on, just highlight whatever you want with your mouse and drag it into your gliider. Photos, text, whatever!

gliider will then bring you deals related to what you're interested in. No spam, no overload. Only the good stuff and just the right amount of it.

If you are traveling with your friends, gliider let's you share your findings with up to 4 people for collaboration, so can have all info in one single place. 

Currently available only for Firefox (3+) as an add-on, its drag-and-drop is very polished and easy to use. Versions for other popular browsers (including IE) are under development, but you can also access your stuff by sending an e-mail to your iPhone.

gliider currently in closed beta and is free. Try it here.
