There’s also a noticeable difference with some beans. Cheap ones are tough and taste almost stale, while nicer ones are creamier and more flavourful.

There are a few default instances in the settings page, and you can add your own as well.

You remove the instance’s domain name from the URL, the same way you remove reddit.com when linking to subreddits. You then append it at the end of the URL with an @. For example, https://lemmy.ml/c/asklemmy --> /c/asklemmy@lemmy.ml

EDIT: Starting with Lemmy 0.18.0, you won’t need to do this manually anymore!
