Another federated single-user bookmarking software. Because it's federated, presumably Betula users can be followed from Postmarks (and can follow Postmarks) as well as allowing interactions with Mastodon et al.

Neat little service that allows you to subscribe to bookmarked toots in your feed reader or automate them with anything that can ingest RSS

"The third-party service Mastodon Bookmark RSS allows you to subscribe to your Mastodon bookmarks via RSS, so you don’t forget to make use out of them. You can even integrate the feed into your favorite Zettelkasten apps such as DEVONthink and Obsidian."
