This section is the staging area for new exploration. Observations about a single article should be posted as comments to that article.
HERE you post new comments or reply to an existing comment, creating a thread. Threads that gain momentum here become fresh lectures in this section.
You are the graduate students helping to write a book, as explained in the blog. Topics of general interest here are likely to become articles in the blog. If you do not specify "not for quotation," you are granting permission (license) for me to quote passages or whole posts in my articles, books, and elsewhere, giving citation credit to your name as you have registered and displayed it here. You may post only material that you own or have a right to distribute according to acceptable copyright law.
Discussion is moderated. Adversarial or confrontational posts, especially those promoting fighting anything, are not acceptable.
You can write whole articles here as comments, but cannot upload text files here as attachments. (I'm working on that.) Mark your comment "for administrator only" if you want to discuss it with me before it is shared with everyone.
