Twitter, like email, as a form of communication is basically worthless due to the lack of authentication and strong identity. At least with email there is enough (semi)publicly visible infrastructure that I can verify more of the message flow (SPF, DKIM, IP addresses), even though all of these are a poor proxies for identity. Perhaps Twitter should add more metadata like originating IP, network, country, device ... A public/private key system to sign messages might add something. At least it might make people think a little more carefully about protecting those credentials if it meant the onus of responsibility (and blame) for malicious messages fell on them if they fail to do so.
