Matt Asay writes "Yahoo! has taken a step beyond Google by opening up its website and other services to third-party developers, the Wall Street Journal is reporting. 'The efforts ... range from allowing users to search other content — such as classified-ad sites — from within Yahoo Mail to allowing them to access online music download services like that of Amazon.com Inc. from within Yahoo Music ... [as well as] redesigning [Yahoo!'s] home page to make it easier for users to tap these third-party services.' It's a good move toward an open-source web, but still leaves Yahoo! and other cloud-based applications vulnerable to obsolescence, a problem recently examined by ReadWriteWeb, which discussed a few good applications that have disappeared from the web. It's good to see Yahoo! becoming more permeable to outside development, but it would also be nice to see its applications outlive the company's attention span or life span." Yahoo! ran Open Hack 2008 over Friday and Saturday. Coverage will be available soon at their developers page.
