Now the challenges become:

1. How can I make a server-to-server ActivityPub call to post my comment from a form on my website, which is hosted on IPFS?
2. Where can I store the private key for the "commenter@mrh.io" user or let people BYO-Key
3. How can I get notified when somebody comments on my site?

4. Much more philosophical: IS THIS REALLY DECENTRALIZED OR IS IT NOT???
