Down with the typical travel sites! Thanks to Dave, I have been acquianted with Kayak. Rather than searching the sites of airlines and tacking on a fee for doing so, this site is completely ad-supported (from the looks of it) so you really are getting the cheapest deal AND are searching a ton more airlines than usual. They have a nice interface to boot!

Why was I using a travel site? Just to schedule my yearly vacation; two weeks in London and wherever else I decide to go while I’m there (weekend in Paris? Ireland? Scotland?). Free lodging while in London? Score.
