Yes, but nobody is running servers with those protocols for free
We had government websites and official channels, but hard and inaccessible.
I think the problem I have is the need for phone numbers and identification to access government comms through Twitter. No one asked who I am to listen to radio (even though some were commercial for-profit ventures).
I’d like to see GSA offer a US gov official Twitter of sorts for instant communication. No ID or Phone required, funded by tax payers.
