Hi FlyerTalk!
My name is John Marbach and one year ago I set out to solve the question, "What are the cheapest flights from my home airport (SFO) to every destination worldwide?".
I am now happy to share with you Concorde Discovery, a worldwide flight search tool. With just one click you can see the cheapest flights to hundreds of destinations around the world. Give it a try, and please let me know what you think:

P.S. I have benefited from the advice of the FT community for many years, so I am happy to "give back" to all of you by building a flight search travel tool. If you have an idea for a particularly compelling feature, let me know, as I am actively building the product myself.
