Nice ideas.
For the first one: would a selfhostable habla(dot)news that you can embed (like fiatjaf's nocoments) fulfill the requirements?
Adding two more Nostr bounties.
## 1st is a long form (kind23) bounty.
A Ghost-blog like self-hosted replacement on Nostr.
This would help companies move their corporate blogs to Nostr and still serve on the web.

## 2nd is a podcast RSS feed mirror/replacement
The main goal is to replace RSS for podcasts, and eventually have podcasts players that understand it. So that users would just follow some pubkey and the authors podcast feed magically appears on the podcast client feed.
