Switching from Reddit to Discourse (self-host)

Run `discourse-setup` from the official `discourse_docker` repo. For migration: Discourse has community importers from Reddit (`scripts/import/reddit.rb` reads a JSON archive of your subreddit if you have one). Discourse trades the ranked feed for a chronological topic list with rich threading; better fit if your community valued long-form discussion over upvote-ranking.

Good fit for
Long-form communities, support forums, and mature subreddits that ran more like discussion boards than link-aggregators.
Weak at
Not a vote-ranked link aggregator — the front page is chronological, not algorithmic.
