A few ideas from the top of my head
- Flairs that can be allowed to filter content in a community
- Major online communites (can be subreddits, or other communities) moving to Lemmy
- Reddit removing old.reddit
- Reddit banning people using VPNs (already happening, see !reddit@lemmy.world )
- Lemmy becoming the reference source of knowledge for a certain domain
Second point is probably crucial, but I don’t see any major subreddit wanting to move here. StarTrek is the exception more that the rule.
You don’t have to implement the platform to provide feedback on how you use it.
Car manufacturer ask drivers for their feedback to improve their models, not mechanics.
