Like skyscrapers under construction dueling for supremacy, Google thrusts out new challenges to its rivals Microsoft and Yahoo! on a nearly daily basis these days. The latest girder falling into place and covered in The New York Times [REGISTRATION] is a forthcoming tool from Google that will allow individuals to search content on their personal computers, taking advantage of delays in Microsoft's increasingly forlorn and untimely Longhorn operating system release now due out in truncated form come 2006. Personal Knowledge Management is the next major frontier in the New Aggregation, and may represent a more pliant "back door" entry into the corporate marketplace than Google has been able to manage with its enterprise-oriented "search appliance." A sideways hint of additional Google corporate plans came when a CNET News article revealed a configuration error temporarily allowed individual email account on their new Gmail service to have up to a terabyte of email storage - 1,000 times their current gigabyte limit. Perhaps just a configuration error or sloppy coding, but the thought also comes to mind that perhaps a release in testing for an enterprise-level Gmail made its way out the door into the consumer production environment. Thinking back to the early days of Bloomberg's sales of financial information services via its iconoclastic data terminals, the way into the enterprise is oftentimes effected by creating cultish enthusiasm at the desk level for content products that I.T. departments wind up having to support due to user demand. The fellows at Google are no Mike Bloomberg, but sometimes old lessons last a lifetime.
