One problem worth solving: how to choose an area to live in ?

I thought to share this with all of you. One of the biggest problems I have constantly faced is deciding which area to live since I have moved many times in my post college days until now. Obviously, there are guiding factors such as place of employment, family, friends, preference (city life vs suburbian) etc. What if there was an app that interactively asks us these questions and suggest some zipcodes/places to live ?

I for example want to know that if I work in NYC and my spouse works in the suburbs of NJ (actually true in my case), where should we buy a house? Logically, should be somewhere in the middle of the 2. but where, why, how ? May be we are not as interested in good school districts at this time? May be I want to live at a walking distance from a major train/bus station ? Possibilities are endless here.
