What I'd like is to require a CAPTCHA for anonymous comments only. Blogger doesn't have that option, and likely won't:
I assume that Blogger, like Google Reader itself, is slowly going the way of Google Reader Shares. Blogger is legacy GoogleMinus, not a good fit for the post-2011 Google. A small but dedicated team doesn't have the resources to keep it healthy.Gordon has some interesting thoughts at his post (and links to some of his older posts). I'd hate to migrate to Wordpress, and Kevin's migration to Disqus was a nightmare of lost comments. I'd also hate to ban anonymous comments.
