For sure it's cooler than the suburbs and I'd recommend any single 20s something person live in NYC over any suburb. But once you get tired of partying and find a nice girl/guy, get established in your career, and tired of paying top dollar for crap accommodation in a stressed out nature-starved environment, it prob makes sense to move out. Though I guess that was always the move anyways - just instead of settling in a New Jersey suburb now you can just live anywhere because f*ck offices.
