I know that communities don’t translate well to Mastodon, I just find it a little odd how it seems to be a firehose of all comments in a community when viewed in Mastodon. I was expecting it to “repost” posts submitted to the community and have comments in the replies to those posts. Just something odd I was thinking about.
Not at all. You can still search and see everything that you federate with, but posts, likes, etc. will not populate on your server automatically unless you follow them. Otherwise, the entire fediverse would have to populate every minute on your personal server. I don’t know how Lemmy handles that.
You also have to subscribe to communities to get their content.
