To me, the Local feed is one of the biggest strengths of Lemmy. It allows having in the same platform a community/instance based feed (for example, Local in jlai.lu allows you to find most of the French activity in Lemmy), and at the same time, I can use "Subscribed" and/or "All" feeds to get a broader view of the Fediverse.

Without the "Local" view, Lemmy would just feel like another Reddit clone to me, where French communities would just be flooded by English-speaking communities. On Reddit, the French community actually had to create a subreddit dedicated to listing all French subreddits, just because the discoverability of non-English-speaking subreddits is just awful by default on Reddit.

And at the same time, I don't see the need for "curation algorithms". The "Subscribed" feed already fills this use case for me.
