Are Newsnight's staff now playing a game of Dare on Twitter?
You may already know that Emily Maitlis deleted a tweet today - one quoting, as if she were backing it, some attack on the Government for being anti-democratic by a controversial Sky hack from February.
But I've just seen another Lewis Goodall tweet disappear before my eyes too.
He was using the Portuguese government to attack the UK government, in a heavily loaded way - as is his way.
And now that tweet has gone.
It's all somewhat toned-down stuff down now on a similar theme instead - and, for him, surprisingly balanced.
If only I'd screen-grabbed it.
What I remember was it calling it "stinging" from "our oldest ally" and adding an extra twist of bias - a turn of phrase that I can't quite recall because I was WhatsApping someone at the time but thought was the absolute cherry on the even-more-absolute icing of the absolutely biased cake.
(Is there a Twitter equivalent of Newssniffer?)
He keeps on doing that.
Many of the tweets he doesn't delete inhabit the borderlands of BBC impartiality, but his repeated post-something-ultra-biased, please-the-Twitter-mob, get-the-applause, and-then-delete-it-without-saying-anything behaviour is especially naughty.
(What do his fans make of their enthusiastic responses vanishing too (collateral damage, friendly fire)?)
I think he's playing a game.
He's very canny, but one day he'll badly come a cropper.
And then Sir Keir can make him his director of communications, and all will be well. (You still heard it here first).
