Just about every major media outlet is currently experimenting with various approaches to fusing high-quality journalistic content with high-quality user contributed content. This can range from simplistic story commenting implementations to more involved user review & ratings systems. I believe that this is the future (if one exists) for print media outlets.
As to hyper-local advertising, there is definitely a market here. I've seen several instances where local community sites have (very) successfully monetized through a combination of local service provider ads and ad network positions.
