I see what Alex is saying and agree with it.

You're looking at it from a follower point of view, but look at it from the members point of view:

- If I want to allow any random person to be able to follow me, I would set my profile to 'Public.' As a Public profile I can control with each individual post who is allowed to see it (not great, need ability to select multiple visibility options), whether it be a public post, or limited to friends, etc. An Organization profile could also serve as a full-time Public profile, gain followers, etc, and the member have a private personal profile as well... Both are managed from the same login, like have a separate page on FB.

Secondly, Una is not the 'traditional Social Network.' The design and purpose is not to replace modern social media, but to allow niche communities, groups, schools, clubs, etc a place to come together with 'social media like' features. 

Do you remember features of FB in 2008 when it was a couple years old? Pretty minimal. I'd say we have a good head start and a much better purpose.
