I think I like 3A the best as well – allow anyone to view (read-only), but to comment, they need to create an account and sign in. I like 3B too, just from a perspective of trying to maintain authenticity on the site. 3A is the best in an ideal environment, but would also allow people to create “fake” accounts just to be able to comment on a site in a somewhat anonymous way (fake email address, etc.). Whatever option you choose, I think it’s important that anyone can read and share true URLs without necessarily having to sign up.
