It's official - with SharePoint clients I am now hearing more "Just make it like Facebook!" and less "Just make it like Google!"
A case in point - I have a client who's making really great use of a customized Task list to handle project requests that come to the IT Department. Today my contact, the IT Director at this client site, was telling me that he wants the developers to be updating their projects "like Facebook" - not only changing the Status drop-down but adding versioned comments as well.
In an interesting governance twist, the developers asked him for a specification on when they should update. (Welcome to the BizarroWorld of Enterprise 2.0!)
Still, the upshot for me is that even conservative SharePoint users are starting to want the social-media look and feel from the tool. A task list is not in the usual catalog of social networking tools within the enterprise, but this client has shown me how it can function that way. I'm looking forward to learning more from my clients and colleagues about unexpected and/or underground ways they are trying to "make it like Facebook."
