Jeff Teper, the Microsoft SharePoint Corporate Vice President has posted a history of SharePoint on the team blog. Note: it could use a proofread, but I think it’s worth sticking with it if you’re not intimately familiar with the product already.
I found a couple of thing particularly interesting:
- The Office 2010 Engineering blog. I’m a beta tester for Office 2010 and love it. This looks like an excellent introduction to the new features
- The Microsoft Townsquare prototype. As Jeff Teper says, it’s interesting for us to see how this publicised work from June 2008 has formed the basis of SharePoint 2010’s social networking features
