There is something about the Yahoo's Site Explorer that makes me feel comfortable, like a pair of well worn slippers. It is with great sadness that I read this great optimization tool is to be given the bullet. If you compare Bing's equivalent set of tools - quite frankly there are massive gaps. Yahoo is dead long live the Bing.

When will Site Explorer shutdown?
We are working with Microsoft to transition organic results in all markets to the Microsoft Search platform. Site Explorer will shut down once all markets are transitioned. This is expected later this year. We will keep updating you with progress of the transition at our Search Blog.
Should I start using Bing Webmaster Center?
Yes, webmasters should start using Bing Webmaster Center.
Does that mean that I should stop using Site Explorer?
No. In a large part of the world, we have not yet transitioned to Microsoft search platform. Hence, it is important that Yahoo! continues to receive your site/sitemap submissions so that search results from Yahoo! are fresh and relevant for markets that have not switched over. In order to continue to receive relevant organic traffic from Yahoo! search results, we encourage you to continue using Site Explorer as you have in the past until we fully switch over to Microsoft search platform for organic results.
