A recent announcement was made by Mike Macgirvin on the current status of the Osada project. In short, it doesn’t sound like a particularly hopeful future for this particular platform:
Osada will be spun off (separated from Zap) and officially abandoned. If you want to take over the project, go for it. The implementation of Zot6 there is now frozen because future Zot6 work (and Zot8 – more on that in a moment) will not be compatible with ActivityPub. At all. As far as I know Osada is the only viable ActivityPub server for events and groups, but Friendica and Hubzilla aren’t very far off.

For those of you who don’t remember, Osada was a new platform with a UI reminiscent of Hubzilla that was specifically developed to support both Zot6 and ActivityPub-based networks. Macgirvin seems to indicate, in hindsight, that this was a mistake.
Zot6 uses Activitystreams (not ActivityPub) as a serialisation format. The actor/object model may be elegant for expressing content, but it falls on its face when relayed between two actors with different permission expectations. ActivityPub folks haven’t encountered this issue because they have no working permissions system.
@blog why the name is "we distribute", if it's about decentralize)
@autogestion @blog It's actually more of a slogan or a motto than anything else. In a sense, distribution here refers to both distributing free technologies, and distributing messages in an open network. While you're right that a federated network isn't strictly distributed in a DNS-agnostic P2P sense, the scattering of messages across many instances is technically still applicable.
@blog so i guess i can take 'try out osada' off my to do list…
@blog good thing i didn't try to spin one of those up ?
@blog Being on Osada I'm kind of disappointed about this. I believe Osada was launched half a year ago and it already will be replaced. Whatever the motivation it's sending the wrong message to users.
@ericbuijs @blog I do understand your frustration about this. Possibly someone wants to continue the work.
Hubzilla could do the job and even better than osada. Osada was a simple hubzilla for large public. Hubzilla is a for a niche of technophile. If you take hubzilla and simplify it. You will win.
@blog Kris:> If you take hubzilla and simplify it. You will win.#Disroot was doing some work on smoothing out the rough edges of the #Hubzilla #UX. Must check back in on that. I was keen to help with this a couple of years back, but got put off pretty fast by grouchy messages from a certain dev about having to "spoonfeed" users …
