Is there an orientation manual for Lemmy? Honestly, Lemmy isn’t even the first DDG result for Lemmy (the first result is the Motorhead founder).
What I really want to know is how to pull in forums from other servers because I’m used to a very curated firehouse of content from Reddit and Lemmy so far seems more about making do with what conversation and audience are available. I found a page from 3 years ago describing a somehwat programmery process to do so…
Also, is there a place to find similar reddit subs? My favorite sub on reddit was the subreddit NOT about literally fucking cars but about the importance of micromobility in a car-dominated landscape. Also: cats who look like Ron Perlman.

Use the “Subscribed” navigation mode by default. And make a habit of subscribing to any community you find interesting.
Then, when you think “I need more content”, hop into “All” to see all communities. Most stuff there won’t interest you; but when you see something that does interest you, subscribe to that community.
Do this often enough and you’ll get a large list of subscriptions, and lots of content, but it’ll be mostly content you care about.
There’s also Lemmy Explorer that lists around 9k communities.
Thanks! I got an app (Voyager) and its greatly simplified everything for me.
Is there a reddit-to-lemmy index? I’m in love with r/wunkus, which is a very idiosyncratic reddit sub. Still, I know from learning languages that every culture has its own unique gems.
