Housekeeping: Comments

A quick note. Seems the spammers have figured out how to defeat Google's anti-spam filter with "comment like" scripts and as a result the blog has been getting slammed lately. Consequently I've taken the action today to require word verification in order to post a comment. Otherwise anyone can still post a comment. I kept it as simple as possible in the past to encourage you slackers. The only alternatives would be to limit comments to registered users or those with Google accounts. My question to you slackers is: Do you have a preference? Word Verification, Registration or Google Account. (Or I can combine the last two, or perhaps even all three, and offer an either or option.) Regardless it's going to take a little more time in the future to comment.
