Late last week, Microsoft released to a select, closed group of beta testers a build of its Windows Live Expo classifieds service (formerly code-named Fremont). Microsoft made the code available to testers at a handful of Washington-state-based companies and organizations, including Boeing, Safeco, University of Washington and Washington Mutual. Microsoft subsequently pulled beta access for some of these customers, according to a report on the LiveSide.Net. What's going on? We're not sure. But the Redmondians are maintaining that a public, nationwide beta of Windows Live Expo is on track for this spring.
