Walt Mossberg, Kara Swisher and John Paczkowski launched All Things D this evening. I met with Kara and Walt in Washington last month to update them on Sphere. As we talked, All Things D felt like a natural partner for the Sphere Related Content plug-in. The site, powered by WordPress, is really well done. We’re very excited about All Things D as Sphere Related Content is working well and the exposure presents another opportunity for a broader audience of tech readers to connect to some great blog content. It’s also a pleasure to be part of a team of folks including Mule, Automattic (WordPress), Alex King, Brian Oberkirch and Raanan Bar-Cohen – all played a role in getting Sphere integrated into the site just in time for launch.
