I travel a bit for a work and for goofing off, and hate paying too much for airline travel. I also want my choice of times and flights.

Enter Kayak. One of the best examples of Web 2.0 design, it’s simple, offers my options to change my search on the fly, and it’s fast. I love the site. I don’t know how they make their money, because sometimes I book somewhere else, but whatever they are doing, keep it up.
