Ok I do think one way BSky is *not* like early Twitter is that on early Twitter if you said you liked or didn’t like a thing most of the engagement was you finding your people but on BSky as with all other networks, a significant share or even most engagement is people who are NOT your people

They have fired the staff of the CDC’s Morbidity and Mortality Weekly Report and 70 Epidemic Intelligence Service officers, who are disease detectives that respond to outbreaks around the world.

I cannot emphasize enough how dangerous it is to dismantle our disease surveillance infrastructure.

Walking through Prospect Park tonight, astounded to spot what appeared to be a mouse scampering up a tree. Looked closer and realized — it was actually a flying squirrel! First one I’ve ever seen in the city. Too dark for photos but wow was that cool.

I’m never not going to reshare a national news story about SterlingFest, the annual celebration of the writer and tv creator, held in his hometown in Broome Co, NY, of which he said:

“Everybody has to have a hometown, Binghamton’s mine.”

His slip of the tongue reveals who’s really in charge. trib.al/mIvP0yE

“Illinois governor says we’re provoking actions that are unlawful,” Miller said on CNN. “If I put federal law enforcement and National Guard into a nice sleepy Southern town, is anyone gonna riot?”

Garage Project is an NZ brewery but now distributed in Australia; I think their Aus arm is based in Melbourne (I belong to their Fresh Club and got this in my monthly order)

This might be the single greatest beer name and label of all time

I am drinking well tonight, friends
A beer by Garage Project called Rain, Steam, and Speed; the label riffs off the JMW Turner painting of the same name with a steam engine rushing through the landscape Beer label blurb for the craft nerds. It’s an “English style IPA” that is “from back when malt mattered”

There are four house martins feeding above my head. They’re six inches long and are about to travel 6,000 miles. That’s about 63 million times their body length. The lunatics.

in 2011, the president of antifa hired me to give fashion consultancy to the organization. i recommended everyone wear navy suits with tan shoes, dress sneakers, and golf polos with slim chinos. if you arrested everyone today wearing these things, you'd destroy antifa

Died (alas!) on this day in 1550, Georg Pencz, painter & printmaker of Nuremberg. Here, his portrait of his colleague Erhard Schwetzer in 1544.

I have managed to attach an extra day in Leiden to my conferencing, which means I spend a day touristing abroad and eating out, which always feels like such a strange thing in the middle of term. But really nice.

A lot of people have asked about the
book I was working on. The truth is, I lost
it when my friend who was helping me
write it passed away. I didn’t know how
to talk about it until now. It still hurts,
but I appreciate everyone who believed
in it. Maybe one day I’ll try again. 😊

Sad to read of the death of William Blissett, with whom I shared many a cup of coffee in the Robarts Library cafeteria at Toronto. He was a kind and generous mentor.

I love it when there’s clearly been a years long, nationalistic edit war and the powers that be have had to step in with a solution that satisfies no one but at least stops the more bellicose nonsense.

Hey, you idiotic propagandists at the New York Post:

God Bless America isn't the national anthem. It's a SHOW TUNE written by Irving Berlin.
