Twit.
I pretty much have no stomach for the way politics is being corrupted by the two biggest social media sites. F6k, I stay off of completely.
But Twitter, it has kind of a quiet corner in the back where all kinds of InfoSec folks hang out. I find that congenial. But I'm thinking all the worst deplorables are about to start feeling empowered there once again. So I am keeping an eye on what comes next.
