As I've blogged about before, I see enterprise social networking as encompassing four quadrants. As I detail in that post, and will be expanding upon in future posts, there are myriad opportunities for companies leveraging one or more elements of enterprise social networking. Public social media sites offer the ability to interface with customers "where they are," to monitor what's being said about your brand on those sites, and to incorporate those channels into your organization's overall communications strategy.
Social CRM allows businesses to pull data from public social media spaces into their CRM and to use that data to augment existing customer information, gain business intelligence, and drive leads. Social software in the workplace offers great potential with regards to improving internal collaboration and communication. And externally-facing social software enables businesses to combine the benefits of public social media sites and social software to allow customers to connect with each other, help each other, and engage directly with your brand in an owned environment.
