Show HN: Seven39, a social media app that is only open for 3 hours every evening

I wish someone made social media where everyone gets one post every day. Almost no person on this planet has more than one bit of news to share daily with their extended social network — probably not even the countries' leaders. When accounts share every 10 minutes, it's often spam or some inorganic agenda.

Oversharing in natural social networks is penalized heavily, and for good reason - with too much noise and little signal, people get overwhelmed, fear missing out, and cannot agree on anything. Communication becomes a detriment and a chore to the social group. The social group expects everyone to think before they speak, not just blabber endlessly, which is healthy.

Also, replacing the "Like" button/signal with a "Thanks" signal would be good because it'd be better to build a social network based on what people find helpful rather than on what people approve of. I think this was originally Jack Dorsey's idea, not my own.

I'm actually part of a site like this, just a thing a friend of a friend made:

- You can write and edit one post at a time.

- This post, in whatever form it has then, gets published at 8 in the morning.

- You can only see posts for today. All old content gets deleted.

- No comments or feedback is possible.

- Only symmetric relationships are possible: you can add someone, but they won't see your posts and you won't see their posts until they add you back.

- All "friend" discovery is out of band. There are no recommendations, no boosting/retweeting, nothing.

This is obviously not a mass medium, but its reductionism gives it some interesting properties that have made me consider what a good social network would be. One post a day is a fantastic idea.

(I don't know if they intend for it to be named in public, so I'll refrain.)

OK, but how are you supposed to meet anyone new this way?
