Microsoft has finally launched its Windows Live Expo. eBay now has to consider not just the competitive threat of Google and its Google Base, but now Microsoft as well. Although 2005 was a very interesting year for eCommerce, I believe 2006 is going to be even more exciting. Obviously, the Live Expo site is brand new, and so the functionality and inventory of listings is still pretty light. However, like almost everything that Microsoft decides to tackle, I expect Live Expo will ultimately be a decent eCommerce channel at some point soon. For every eCommerce entrepreneur that makes a living selling online and for every company that supports these online merchants, the additional online competition is likely to bring new opportunity and decreased dependencies/risk. For most of us, Microsoft’s entry is a positive event.
