Found a new quarterly journal that looks promising. It is called Fare Forward: A Christian Review of Ideas. The name comes from T.S. Elliot's Four Quarets and the site is written and edited by several "emerging adults" (as they describe themsleves) who are "young people who have graduated from college and begun to enter the work force but who are still facing a period of transition and uncertainty."
