Well, it's been another exciting week here in the Linux blogosphere, not least because of all the many seismic shifts emanating from the vicinity of Redmond. There was the end of the Justice Department's antitrust oversight of Microsoft (Nasdaq: MSFT), of course, marking the end of a historic case and a memorable era in the IT industry. Then -- not coincidentally, given Redmond's new freedom -- there was also its wildly extravagant purchase of Skype, the implications of which still have observers reeling. It's been enough to set geeks' heads spinning, in other words, and that's just what could be observed throughout the hills and dales of the blogosphere.
