As the number of social networks grows, it's easy to be overwhelmed by the effort to maintain each one independently. Each network may serve a purpose to your personal or professional life but it is easy to lose track of the networks you've joined, are managing or are interested in.
For individuals, there is a great How To from Ben Parr at Mashable that provides a good approach to identifying and managing your networks. There is also a desktop solution that I will be experimenting with called Sobees. Sobees claims to "offer an easy unified user experience to get, organize and share information from the likes of Twitter, Facebook, Friendfeed, Digg, Flickr and YouTube directly on the desktop". Sobee sounds similar to Collactive which is a company that offers a robust social media management platform for the corporation.
Finally, for those who support Corporte social media programs, I would recommend reviewing the Forrester Wave Report on Listening Platforms as well as the agencies they recommend.
