Tonight I changed the COMMENT feature beneath each article so that "Anonymous" can no longer comment. Folks will have to be registered with Google, Live Journal or one of the other "Open ID" blogs in order to comment.
I was never too enthused about accepting comments from "anonymous" but I allowed them. Lately, the plethora of nasty anonymous remarks has become annoying, so they are now shut out.
If you have the guts to say something publicly, have the guts to allow others to know how to contact you back. Otherwise, no one cares what you think.
