Someone recently asked if there was a neat way to see where all of the now broken down subreddits moved.
Some moved to Discord, some to Lemmy, and some are somewhere else.
This seems to be a good place to find your communities again: https://sub.rehab/
Have to agree. Discord added a forum post view to popular communities which is sorta like Reddit, but not really. For really large communities, the noise from high traffic channels is tough to filter out.
