The successor to Web 2.0 bookmarking site del.icio.us is here, but this time, it’s built for the open web and the Fediverse — the decentralized collection of social networks that includes the Twitter/X competitor Mastodon and others. Portland-area web developer Casey Kolderup has launched Postmarks, a Fediverse-enabled social bookmarking service that offers a web interface for saving your favourite links and annotating them, similar to bookmarking sites of years past.
But this time, your links and notes can be shared with your followers both on Postmarks itself, as well as other federated social networks like Mastodon or anything else on the Fediverse.
It is interesting to see that the ActivityPub protocol is not just used for microblogging (like Mastodon and similar) but also for social link aggregation (Lemmy, etc), book reading (Bookwyrm), blog hosting (Shuttlecraft), and now also bookmarking.
This is different from social link aggregation where a link is posted and has related discussion threads as well as voting, and is intended for communal use. Postmarks is more a simple link, with description, tags, and optional association to other tags. Any other Fediverse user is then able to follow your Postmarks feed, or searches on the tags should show up as hashtag results. So, the focus here would be more your personal collection of bookmarks.
It is still early days for this service and I’d hope it gets the facility to import bookmarks from a browser (if that is not yet a feature).
