I use Hive as the source of posts. But it must be possible to automate the opposite - that is, post automatically into Hive from other sources. It's a question of writing a plan and coding it. AI helped me with the plan (PRD) and the coding (Astro site using Hive content for blog content deployed to Cloudflare Workers).
I feel like I taught AI a lot during that lengthy process. But my experience supports the original post - it costs very little to create Hive-based apps and websites.
I guess I'll get chatgpt to figure it out. Following you in case you ever write about it.
