AP behaviour to work in the opposite way internet does, makes everyone unhappy.
Caching the same shit on hundreds of servers makes me frustrated. Also, lack of identity authenticity makes thing worst.
If we can solve this two issues, we are done for the next 10 years without adding anything else who could break.

Maybe we can use GPG to sign posts, by having an inbox for public signatures, storing private keys on back-end, already encrypted by the client. The caching issue, have no solution (yet) for me.
