It is seemingly impossible to sell a client on the idea of Social Media without good case studies to back up your claims.

Unfortunately, case studies are hard to come by. There is lots of anecdotal evidence, and we have all seen what impact social media can have if you are not paying attention.

But what about those times when a client has applied the Social Media philosophy, and got spectacular (or not) results?

This page is a collection of case studies I have found scattered across the web. Hopefully, I will come across enough good new one to keep this page updated regularly.

Socialtext manages a wiki for case studies, and there are five there now. I list them below, with a short summary, and a link, so you can pursue them in your own time.

Case Studies:

• Angel.com
  Angel.com required an easy-to-use wiki solution with enterprise-class features delivered as a secure, reliable hosted service; Socialtext provided a robust wiki platform for collaboration between Angel.com’s employees, with its business partners, and as the foundation for its public community.
• AT&T Collaborative Integration
  This case study provides an overview of the first 5 years of an evolving journey with Enterprise 2.0 applications within a large telecommunications company.
• Boston College Case Study
  Boston College required social software to stimulate the education process & create lively interactions between students and faculty; Socialtext provided easy-to-use platform for wiki collaboration that seamlessly integrated with email, RSS feeds, search and other popular web-based technologies.
• MWW Case Study
  MWW Group required rich collaboration tools for managing projects, tracking status & collecting relevant competitive intelligence into a searchable knowledgebase; Socialtext wikis provided easy-to-use platform that users could get comfortable using in minutes, plus integrated with traditional tools like email, RSS feeds & search.

Now is Gone also maintains a blog page linking to case studies. It is definitely worthwhile checking out. I have chosen some of the best entries and listed them below.
