Currently you can only participate in many decentralized social medias if you have money by making posts directly on the blockchain, most that use alternative methods don't have methods for accessing that account from other devices. This makes the social media restricted instead of free, leads to fragmentation, and congests the blockchain networks for all other transactions.
Social media posts do not need protection from double spending attacks, therefore Merkle-CRDTs are a perfect canidate.
I also believe that everyone should run their own node, however it is extremely difficult for non-technical people to set up and use. In fact, I believe it can be difficult even for technical users.
This submission is an iteration on creating a seemless user experience to interact with crypto-secured applications, not just blockchain ones, though it is also meant to bridge the gap between the two.
While general posts do not need to be stored on the blockchain, linking the two allows easy integration for parts that do, such as access to licesnced templates, music, etc. as well as sales of real world goods through such social media.
