Lawrence the 47% is the largest primary usage. But, using it as a broad social platform is not one of the top uses. You should have that stat at the top of your head, of all people. Care to share it?Yes, those within the SharePoint world know the beating and short comings, but most organizations I talk with and work with feel like they are the only ones with problems with it. Most believe the hype that it can do the wiki, blog, open sharing, MySite, etc. easily and passibly well.Lockheed, as mentioned, built on top of Sharepoint (one of the most expensive builds for an organization I have run across yet, not cost to MS).One of the points is turning to a Telligent type service that builds services on top of SharePoint is a good option that many organizations consider and have had success with. The cost of trying to do what Telligent type tools on top of SharePoint do is much less and has more success than opting to go it alone and develop those capabilities.There is a lot of understanding of how social tools should work and need to work in enterprise (deeply based on how people interact with others and with interfaces) that must go on top of the technology platform. I have deep interest in that story and that understanding, as it is one I rarely see inside enterprise, but I see with in the makers of the social tool products.The point I hear over and over from those trying SharePoint to accomplish enterprise 2.0 functionality (open social interaction, ease of use, ease of working in the flow, sharing collectively, aggregating in context, and eventually getting to collaboration) is not the platform on its own to do this without very deep pockets for development. Lockheed and Wachovia are the only big deployments I know that went down this path.Those I talk with who have had heavy talks with those two organizations about those deployments have said they are going another route in their own organization. They believe other options will be lower cost, deliver something that is quite close to what they are looking for, and have lower up keep in the long run.
