Newcomers

For me (I think some of those might have been introduced to Lemmy too in the meantime. I haven't been checking):

1. Feeds!
   If I want to check up on what's going on in news, I open the feed with news. When I want to read posts about games, I open games feed.
   Those can be private (your collection of communities), owned by you but shared with others, or you can subscribe to public feeds of others. And those federate, so you can follow Skavau's hard work from any PieFed instance
2. Notifications (opt-int - you click what you want to follow)

• per post
• per feed
• per community
• of responses to your comments and posts
• ...
• you can also set reminders about posts and comments

1. Merged posts
   I no longer have to jump through all the cross-posts, the comments are all together under a post. And there is info which community block starts, so you still get the context of the comments
2. Events
   Although not often used, this is super cool feature, where you can mark a post to be an event and it will create an .ics file you can use with any calendar app
3. tags
   I do hope Threadiverse gets closer with Mastodon (while staying a Threadiverse) and I think this is a step in right direction
