Here are a summary of the changes:
- You no longer need a Google account to leave a comment, but there is a message encouraging you to leave a name/URL so people can tell your comments from other people's. Sadly there is no way to force this in the blogger comments system currently.
- I have removed moderation. All new comments will be instantly posted to the blog.
- I have removed the captcha barrier for posting comments (but may reintroduce it if spam becomes a problem).
- I have modified the "x comments" link that appears on each post so it encourages people to leave a comment.
Lets see how it goes. My guess is that I will need to re-enable captcha at some point, but Blogger's anti spam system may be good enough to not require that.
