Is this the first major public forum to go public?

Maybe if you define "forum" in a way which excludes social media sites like Facebook, but that feels like an artificial distinction.

It really does, there are facebook groups that have 80% of the functionality of reddit on specific topics, much like reddit, with discussions like reddit, and sharing media, just like reddit.
