Ask HN: Do away with Social Media sign-ins?

Me and my friend are debating over if we should allow our q & a social networking site to be readable and accessed by the open public without any sign-in.

Personally, I think we should allow everyone to be able to view the site the content of our site Wsid.com (like reddit) without having to sign in. Obviously via this viewing experiencing one would have to sign in to post content.
