Adult Social Networking
This would be a social networking site targeted at adults and professionals, generally people from ages 25 and up. It would have all of the features of Facebook such as a network system, groups, events, photos, etc., but people would also put their jobs, professional skills, or even a resume if they were looking for a job. Companies could pay to do power searches for people, but for people to join would be completely free.
This website would be a mix of LinkedIn and Facebook. It's like LinkedIn in that people can find jobs and make connections. It's unlike LinkedIn, and like facebook in that it would be completely free and you can search for anyone, but you can only see very little information until you friend them - but you can friend people. LinkedIn only allows you to friend people in your networks unless you pay. And again it's like LinkedIn and unlike facebook in that it's targeted at professionals and not students, and there would be no News Feed (it records everything everyone does and shows everyone else).
I see a future where every single professional has his or her network of contacts online, business and personal, and can find people and communicate extremely efficiently and easily. If you meet someone in line somewhere, or on an elevator, or at a convention, all you need is their name and you could find them on this site. You would be connected to your co-workers or your independent contractors, or even your employees through this site. People would find it strange if you weren't on there. But the thing that would have to make this work is it's target of professionals and adults, and probably a little Web 2.0 hype mixed in.
