I was really excited to see Larry Dignan's announcement that Oliver Marks has joined the ZDNet blogging team. I've known Oliver for a few years, first meeting him while he was managing the Sony PlayStation team's collaboration extranet.
He's a great person with deep experience in collaboration technology, having rolled out things like Jive and other tools. He also knows quite a bit about open source, having managed teams with heavy reliance on open-source technologies.
Check out his new blog on collaboration. Well worth a read. Where else will you read about the Crimean War, super poking, the price of a barrel of crude, and social networking, all on one page?
