Joost de Valk has published some great questions and answers about SEO and WordPress on his blog. Joost used his Facebook page to gather questions from his fans and followers for 24 hours (around 50 questions were posted) and then answered some of them in a post on his website.

We think the idea is great in general and Joost should definitely do this more often, although it would be more interesting if the questions and answers (together with the people) were in one place for a conversation rather than question-answer. We loved how Barry from the team did his Ask Barry session at WordCamp San Francisco this year.
