Microsoft is buying Groove. (news.com, March 10th 2005). See commentary by Stephen O'Grady (Redmonk), which discusses the potential threat to Lotus and other tools in the collaboration space. See also commentary by Michael Sampson, which discusses some of the technical options now facing Microsoft.
But I think there's something else interesting here. At Groove, both Ray Ozzie and Michael Helfrich have been enthusiastic proponents of the concept of Power to the Edge. See Ray's review of the original book by Alberts and Hayes. Ray is now becoming a senior manager at Microsoft, reporting directly to Bill Gates. Michael left Groove at the end of January, for a mission that remains unclear to me. Meanwhile John Stenbit, former assistant secretary of defense, joined the board of directors in November 2004 (press release). (He is also on the boards of Cryptek, McDonald Bradley, Mercator Partners, SI International and Viasat.)
So what is Microsoft's role going to be in providing a platform for the Edge Organization? This is something we are going to have to explain and explore over the next few months and beyond.
