Matt Cutts from Google started his blog about a year ago. As soon as he started it, he has drawn an immediate fan base of active readers and participants. Jeremy Zawodny of Yahoo! had a blog long before, since June 2002. Jeremy has a huge following as well but a different following from Matt.
Matt focuses most of his blog posts on helping out Webmasters and SEOs with Google. Jeremy talks mostly about what he wants to.
Matt posts instructional videos on SEO topics. Jeremy posts recaps of his instructional flight lessons.
Matt announces Google data center updates. Jeremy announces new jobs open at Yahoo! within his department.
Matt geeks out on search algorithms. Jeremy geeks out on MySQL optimization.
Matt has been focused on search related topics since being with Google in 2000 (or so. Jeremy has jumped from division to division at Yahoo!, not always focusing on search related topics.
Is Jeremy the Matt of Yahoo!? I would not compare the two. Yahoo! has Tim Mayer, who is more up Matt's alley, in terms of communication. But Tim is not an engineer. Jeremy is a blogger but is not that focused on search. There are those who work under Tim and speak at the conference, but they don't have blogs. Of course they blog at the Yahoo! Search Blog, but not at their own personal blogs.
