In a new blog post, @imanijoy provides a deeper dive into the design process for Collections, and explains what we’ve included (and things that are left out) for the first release. We’ll be enabling this feature on mastodon.social next week, and rolling it out more widely in Mastodon 4.6 very soon. We’re excited to hear what you think!

@Mastodon Speaking as a contributor of @fedidevs which currently hosts Mastodon “starter packs” at https://fedidevs.com/starter-packs/
We're working on interoperability with Mastodon Collections and will use the same technical mechanisms in the future, but completion of this work is months away. We endorse people migrating their Fedidevs starter packs to Mastodon Collections wherever that makes sense.
We were involved with the backend tech behind Mastodon Collections. No competition and no bad blood! 🙂
@Mastodon In the long term, @fedidevs will most likely focus on capabilities outside of the design of Mastodon Collections: longer lists, curation by multiple owners, etc.
Smaller packs more personal in scope might make sense to be moved to a Mastodon Collection. We'll leave it up to everyone to decide which service fits their needs better.
The safety features mentioned in the post (be notified when you are added, ability to remove yourself) will also be provided by our implementation.
