"I’m still writing the actual content for Amazon Reaha at some point in the hopefully not-too-distant future."
I'd just be patient and let it happen when it happens if I were you. Potentially you could donate to his tip jar and get some sneak peeks.
But In the mean time there's plenty of good upcoming content in the horizon. And there's a lot interesting stuff you could see and potentially review among the event submissions.
Well I've played a lot of TiTS and there's still some goodies I haven't completely discovered yet. I assume there might still be a lot of unexplored territory for you too
Maybe try to talk to more npcs? Test out a few TFs? Maybe your boundaries will widen?
And like I said lots of good stuff coming up/up for review in the event submissions
