Someone suggested using different instance accounts like multi reddits. Then you just jump between accounts, depending what stuff you feel like seeing then.
Another idea was making accounts on instances that interest you and using their local posts to find other things that are similar.
Eg I have a feddit UK account which I plan to make a localised UK focused one.
I just saw someone on one of my fb groups saying she’s heard a lot about reddit lately and wanting to make an account and asking how it works.
I tried to ward her off but the negative press just seems to be enticing new users.
