Dating and Social Networking Mashups are very popular and they make your site more attractive for your members and newcomers. Nowadays, niche social networking is very popular and socializing sections like: Groups, Events, Forums, Blogs are very common features at well-known sites like Facebook or MySpace.

Most of the Networks are localized and provide a wide range of events for their users. Other sites offer mapping for the latest events in the area. For example, deciding when and where to go out on a Friday night just got easier for San Francisco consumers with a new, mobile map application that automatically shows where the hotspots are.

Sense Networks' CitySense, which just entered alpha, gives users a real-time view of how busy the city is as well as where the busiest places currently are. There's no need to sign up--users simply download the free application onto their Blackberry (iPhone support is coming soon) and view a "heat" map of activity throughout the area, linking to Yelp or Google to zero in for more information about the hotspots. A billion points of GPS and wifi positioning data from the last few years complement the real-time feeds underpinning the technology, which operates on Sense Networks' Macrosense platform.(Macrosense, which is designed for analyzing massive amounts of aggregate, anonymous location data in real-time, is already being used in the business world for selecting store locations and understanding retail demand, for example)

Focusing on nightlife, the next version of CitySense will be able to tell users not just where the activity is, but where people like them are concentrated.
