I think it would be great to see third-party applications pick up the slack in the meantime. Basically, having an app that lets you use any supported fediverse account to interact with a specific paradigm, whether it's community threads or microblogs.
For example, I'm replying to you now from Mastodon since I want to use federation to the fullest, but copying urls from Kbin every time is laborious. Having an app that uses my Mastodon account and presents like Kbin would be the dream.
