I've attracted a clown who's having a harmless dialog with himself in comments.
I don't mind a little clowning and I don't even care who the clown is, but I would like repeat commenters to be identifiable by, at least, a pseudonym. Therefore I've changed the comment setting on this blog to require an OpenID or Google Account to comment.
Let me repeat, you can still remain anonymous, but you'll need a pseudonym.
By the way, I haven't heard from my pen pal in awhile. BD, I'm curious, what are your thoughts on the Lion Launch Pad affair?
