#osada is shaping up to be a pretty decent #activitypub client. We're still at least a week or two away from a public alpha but things are moving forward at a steady gallop. Groups, photos, videos, events, conversational (FB style) structure. Native WebDAV and federated single sign-on. A few other goodies are available from the "app store" (in our store everything is free). It also has a working permissions system and several privacy options because it's also a #zot6 client. I'm trying to make it compatible with the plethora of Twitter-style microblogs, but some of them have pretty brutal HTML filters. We'll see.
