The next wave of social networks will most likely be decentralized. At the moment the concept is not yet clear, so no company to follow yet.

Yes, I like the concept but as I mentioned before can't see ordinary people using it.

I mentioned in another comment the idea of a blockchain based system.

At the moment the Bitcoin blockchain is 40+ GB, meaning everyone involved in the network should have it locally. This is not possible for mobile devices.

Relying on blockchain technology is needed only when everyone should trust on something, but once you have the peer to peer connection this is no longer needed.
