I'm working on a "decentralized" app that allows posting messages.
The posts are stored in the blockchain and not censurable to some extent.
Posting a message requires a transaction which implies fees but this would also prevent spam.
The whole app is hosted on github pages and open source: https://github.com/alucao/decon
I'm exploring a similar project, having a "decentralized" website (hosted on github) which saves users' data in the blockchain itself and then provides that same data to other users through public APIs and/or from actual blockchain clients.
Wonder if there is actual use or need for such thing.
