I have changed the commenting feature on this blog to require registration. Registration is easy and can be anonymous. You only have to do it once. You can be identified by a screen name. Blogger doesn't give me or anyone else access to registration information.
I am doing this so that commenters can be identified in some way other than "Anonymous who posted at 1:41 p.m." This will also act as a restraint upon those who seek to use comments on this blog as an astroturf device, posting the same message over and over to simulate grassroots support for a position that has little or no true grassroots support.
