A while back, I wrote up a design for bridging Microsub clients to traditional feed reader backends. Fast forward to a few weeks ago: I hacked together a bare bones prototype at IndieWebCamp 2018. Fast forward to now: I’m launching Baffle!
Right now, it only supports viewing channels and timelines. If there’s enough interest and usage, I can add channel management, muting, and blocking. I’d also consider adding Feedly if I hear enough desire.
