Yahoo announced today a new blog for their Yahoo! Search division. The blog can be found at http://www.ysearchblog.com/. Currently they are accepting comments and trackbacks at the first entry by Jeff Weiner named The Engine of Possibility. Jeremy Zawodny was instrumental in helping his company launch this blog. Of course they are using the MovableType "publishing platform", smart move - in my opinion. Unlike the the Offical Google Blog, Yahoo actually has links to "Industry Sources" such as Search Engine Watch, WebmasterWorld, many other news resources and blogs (including this one).
Forum coverage will pick up on this topic, but currently the following forums are discussing the announcement of the Yahoo! Search Blog.
