Matt Cutts is about to record some new learning videos. And have called users to post questions or suggestions for videos via a Google Moderator page, where in addition to posting, you can also vote topics up and down. Questions need not to be about search/SEO, and can be generalised also. “I won’t be able to answer every single question, but I’ll tackle several popular questions plus a few interesting questions. Please ask questions that lots of people would be interested in, not just questions about a specific site. If you can ask about a topic that requires more in-depth answers, that would probably make the videos more interesting too.” As of writing this post, total 94 questions were posted by 130 people, and 1,932 votes.
