I have hinted previously that I may change the comments policy due to the excessive amount of "Anonymous" comments on the blog. As an interim measure while I research ways to possibly upgrade the blog, I've changed the settings for making comments, so only registered users can make comments (using Google, OpenID, LiveJournal, WordPress, TypePad, or AOL). I encourage you all to continue to make comments on any posts - there have been some lively debates lately on a variety of topics. My goal with this new policy is not to censor comments. Open discussion posts will also be introduced soon and used from time to time (especially when I get bogged down with other tasks that keep me from doing new posts on a regular basis). However, I think the discussion will be more productive if the comments are not anonymous. Thanks for your cooperation.
