Travel Help
Adioso is a simple travel site that lets you search easily and quickly for the cheapest flight available. It lets you search with a variety of methods, including setting a specific price or lower for airfare. Offerings are slim for now, but this is definitely worth bookmarking for future reference.
Stay.com lets you create your own travel guide. From hotels and restaurants to fitness centers and children's museums, Stay.com lets you create a travel guide based on what YOU want to see. You can also suggest attractions to the creators. Cities on offer are few right now, but the major tourist cities are included and if you're starting out clueless, this is a better place to start than a packaged tour that makes you go places you'd rather not.
Something not travel related: If you don't already have a customized homepage, Start IO can help you get started. Just register and Star IO will walk you through setup. The most popular links are already included, but you can easily add links you'd rather see at start-up and remove links that are irrelevant. You can also customize start pages for group use.
