Famichiki and Mastodon in general get complaints because it's not as wide as other SNS. I get that. However, a downside for one person is an upside for another person.
What Famichiki offers is people who, regardless of their level of anonymity, are acting in good faith. They are real people giving their real opinions without playing to the algorithm. That's why I am 100% fine with meeting with any of you in person.
