If you're reading this, you've probably seen some of the Webmaster Help videos Google's Matt Cutts has done. He regularly takes questions from webmasters about various Google behaviors, and uploads responses to YouTube. Sometimes, they're longer in more in depth, and sometimes they're quick and to the point. We usually share them here as they become available, as they're often filled with useful information, even if it's not always completely new info.
Cutts took to his blog this afternoon to announce that he's currently taking questions for the next series. He says he plans to record some videos next week, and asks that people submit their questions via this Google Moderator page.
So, now is the time to submit a question if you want a shot at getting an answer from Google's Distinguished Engineer and head of web spam. The man can hardly walk through the hallways at an industry conference without being bombarded by people with questions. His answers are clearly in demand. Here's your chance to get an answer without having to wait in line.
Or, of course, you can just check out the Moderator page, and just upvote the questions you think are best.
