My impression of mixi2 is that they've done a lot of research on Misskey.
The elements that are considered to be advantageous to most people compared to Misskey are:
- App available (official only, no room for hesitation)
- Closed
- Simple and excellent UI
- Lightweight app
- Strict rules on prohibited activities aimed at the general public
- Managed by a long-established SNS company with strong capital and profitability
The next step is an introduction to potential followers and communities that may be of interest. This is also simple and easy to understand.
It also seems unlikely that posts that focus on current events, gossip, or attract negative attention, that incite desire for success or exhibitionism, that exploit loneliness, or that arouse sexual desire or incite crime will be tolerated.
It would be great if this kind of atmosphere could be maintained forever.
