Yeah that’s the one catch! There could be a way to make an app that accesses the Read Write.as API endpoint, stores posts with your Read Write.as response hashtag, and lets you render them however you’d like. This app could be for public or private use.
Wild, but I’m imagining the private use almost being like an inbox or DM app of sorts but just for Write.as. Your “account” is just a hashtag or two that your app follows. You could even do this for an app that searches post bodies for your name or blog’s url instead of a hashtag.
We have a Glitch app that searches Read Write.as (here) - could be a good base to make something like the above!
