It must be the winter blues
not another war for oil
Gotta be seasonal depression
Not the digital rape of women who dare to exist on the Internet
A little Vitamin D will do the trick
While the tech bros sacrifice humanity and the natural world to their AI dieties

@zohrankmamdani.bsky.social, could you please establish an official NYC Mayor account on Bluesky and post everything your office is currently posting on X over here?
And please remove all city accounts from X, which has become a CSAM creation and distribution site?
No money for Musk, ever, please.

Rough vibes on this website today, likely because people feel Hopeless and Helpless Because Can't Stop It and No One Who Is Supposed To Is Trying To So Now We're Fighting Each Other™. I recommend activities such as book, or potentially instrument if you like instrument, or even do talk on phone.

I stopped using twitter a year ago and tonight I fully deactivated the account.
Goodbye indeed, thanks for all the fascism.

My whole life, advocating war has been fed to me as “the adult position,” akin to drinking your coffee black or reading the business section of the newspaper. Let’s be very clear — war is the childish nonsense of impulsive destructive idiots playing baby-brained video games with real human lives.

Instead of whatever this is, we should have a government getting lots of new homes and apartments built, lots of clean energy built, lots of high speed rail and transit and bike lanes built, human rights for everyone, economic & healthcare opportunities for all, & innovation that leads the world.

Portland folks, please share - looking for this kitty's home!
My house has a new familiar. If you are near 39th and Holgate in Portland and missing a delightful black kitty, this guy or gal seems to clearly come from a home and is also desperate for food and shelter

It was such a joy to celebrate Hanukkah with Mandy, Kathryn and their son, Gideon. As Jewish New Yorkers across our city prepare to light candles and mark the seventh night today, I wish you and your families a Hanukkah full of light and love.

This is obviously a, ah, provocative take on the subject, but it indeed an enormous societal problem that children have stopped walking or biking to school. There are plenty of individually rational reasons parents might drive their kids to school, but, in a wider context, no good reasons.
