altonzheng got it right I think when he wrote I had a similar revelation a while back with Snapchat. Users complain that you can't create groups to send to, you have to manually select each person. I like this - it means when you receive a snapchat, you know that person intentionally selected you to share a part of their life with. It adds a subtle but meaningful quality to a message that could be considered spammy and impersonal https://news.ycombinator.com/item?id=10860501 https://news.ycombinator.com/item?id=10860501 Snapchat requires you to select who you want to see your snap. There's no facility to push into everyone's feed. I'm not sending it to my "Friends" or my "Family" without consideration. You aren't going to click 200 people, or 150, or 50. You're going to think "These five people really love hiking." Or "My cousins were talking about adopting a husky." Or "Last time I burned bacon like this was with John and Jane." Saying "you can only have 150 friends" wasn't the key to a more personal experience. It just meant there was a hard limit on how many people could spam you. The key for me is the tiny marginal cost of sending something to N+1 people, so instead you choose more thoughtfully.
