We have just added a comment system to our articles, which enables you to post comments via Facebook (which you can also use with yahoo.com, aol, or hotmail accounts).
We never really used to have comments allowed here because I didn’t appreciate the idea of us, with real names and contact information, versus anonymous “commenters” who take no responsibility.
With the Facebook system, however, I hope the real people-based scheme makes it possible to have productive discussions if there is a chance. And we have always wanted to communicate with people more. Let’s see what happens, hope it works out.
