In reply to Jeff Chandler.

Some sort of comment CAPTCHA (if you will) would be cool. That is, in the sense, someone reads an anon comment (name, etc. hidden) and determines if it's kosher or not. The point being, this could help lift some of the burden off the site owners / admins. Kinda reminds me of wanting to use basic BuddyPress as an intra-site commenting platform.

I'm not exactly sure how it would work in practice, but in theory is kinda makes sense.

All that said, why not Disqus?
