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.
One major thing I miss from Reddit was the powerful search bar that I had with old reddit+res.
Hopefully now that plugins can be developed this will be fixed
