Jay just posted a blog post, called Building enterprise social communities with Drupal, sharing a white paper that we have written at Acquia. In this white paper, we answer questions like: what kind of social features Drupal supplies, why Drupal is the best choice for building a social site, what Drupal modules are useful when building a social site, and some examples of successful enterprise Drupal communities.
The reason we wrote this white paper is simple: many of the enterprise organizations that we talk to ask us these questions over and over again. Building social business sites is a very hot topic in the enterprise. The work environment in these organizations is evolving, and increasingly more, people want to connect, create, share and find people and information relevant to their work. Needless to say, not all social business sites are equal — some are team collaboration sites, some are community sites, and others might be networking sites. They can exist behind the firewall for internal teams, or they can be external facing sites to engage with partners and customers.
We wrote this white paper because we wanted to demonstrate that Drupal provides a great platform to build these kind of social sites for the enterprise. If you are interested in building a social site for your enterprise and don't know where to start, have a look at our white paper. Also, if you've built, or have a Drupal site around which you have built a successful community, we'd love to learn about it, and learn from it.
