You may have heard that craigslist.org was recently purchased by eBay and the business model is no longer a free one in some cities. Craigslist has had a monopoly on online classified ads, so eBay thinks it would be smart now to charge for postings. Well, before that gets started, Microsoft is now stepping in with “Windows Live Expo.” It will be another free online classified service. It will keep Craigslist honest and hopefully blow apart the new fee-based approach. Other ideas are also popping up from AOL, so there will be lots of competition in this area. And competition is always good for the consumer.
