Today's article

First of all, I'd like to thank you all for being so involved on today's topic - it was very exciting to see such profound interest and to hear such shrewd questions!

On to business now: I'll post the questions here, grouped into general topics, and hopefully we'll get to them all next Friday although most of them are so fundamental that decades of research have only begun to scratch the surface. Please feel free to post follow-up questions and comments!
