Close, but with the added possibility to change the data (like a website/blog/chat) and not only have static data.

So on this protocol, you can have a website with a link to my website, who has a link to yours. Maybe that doesn’t sound crazy cool :-) but filecoin, IPFS etc just does not have that functionality (with them you have a key/link, and it is locked to 1 data. Fix a typo in your text and you have to redistribute a new key/link on the old web or similar, it’s totally static), and for me it’s a must if you want to provide a functioning “new web”.
