The biggest technological revolution of our lifetime is underway and it's not AI:

Minimum parking requirements create financially insolvent land use patterns. The two apartment buildings on the right generate six times more in property taxes than the big box store on the left, while occupying almost half the space! #BlackFridayParking

When the new bike lane is protected:

you should support liberal currents!

While NY is considering mandating two-person trains, the DC Metro not only already operates with one person, but recently reactivated its automatic train operation system. Now, continuing to follow best practices, Metro has announced plans to move towards driverless trains. tinyurl.com/yft73mru

when we say we want more streets to be pedestrianized, this is what we mean

Liberalism is good, actually.

Learning that Annemarie Gray (no relation) of Open New York, NYC's YIMBY group, has been appointed to Mayor-elect Mamdani's housing transition team. This is FANTASTIC news!

How can you not love a website that includes Land Value Tax in its survey of reader policy preferences?

Really important to stress that the Crown Jewels of the US higher education system were never the Ivies or elite SLACs (other countries have equivalents of these) but the well-funded, large, cheap, and excellently staffed public state university systems bringing high quality education to the masses.

The funny thing about this meeting is that Mamdani didn't back down on a single policy point or anything he's said about Trump.

As mayor of New York Mamdani controls access to the one thing Trump values above all else: tickets to CATS.

THE POPE HAS THROWN A RAVE I am now experiencing FOMO about the Pope's rave god, cyberpunk novels of my teenagerhood weren't weird ENOUGH

In an effort to remain one of the worst Councilmembers, Cindy Bass is filing an appeal to prevent the replacement of this non-historic 1940s airlite into 13 new homes, which is even by-right legal under zoning. This is why we have a housing crisis Mayor Parker! phila.legistar.com/LegislationD...

Congestion pricing will be a popular issue in 10 years.

Micro-mobility is an anti-fascist tool, you heard it here first.

the fact that nobody cares when a driver kills a human, but people light Waymo on fire when one kills a cat is an opportunity. the reactions to Waymo accidents are way closer to how we should react when drivers kill people

One thing that's neat is that disabled people have very normal voting habits in comparison to the able bodied population, in fact, to the extent there's any lean at all, its very mildly right wing

Philadelphia had 134 traffic deaths last year, 59 of which involved pedestrians hit by vehicles.

I just left a voicemail for the Scranton mayor's office suggesting they reconsider elimination of the city's split-rate tax, as elimination would slow growth, embolden speculators, and encourage blight. Encourage y'all to do the same. (570) 348-4101

This is particularly disappointing because it’s happening just a few years before rail service returns to Scranton. Would have been a great case study in the power of a land value tax to spur TOD.

Trump in a room with a very charismatic person results in like half a day of Trump agreeing with everything that person said, so this has the potential to be very, very funny.

Scranton is trying to scrap their land value tax, while they also express concerns about their longterm fiscal health. This is awful policy. archive.md/hhCRM

Today is the day to repost this meme about International Men's Day, one of the most unironically wholesome memes that has ever been made. Shoutout to all my fellow champs, chiefs, and kings. ✊

BEST DAY EVER!!! The award is called the Eric & Wendy Schmidt Award for Excellence in Science Communications & is run by @nationalacademies.org & @schmidtsciences.bsky.social #scicomm #phdstudent

there is not a single Republican legislator who is a worse person than Trump is and whatever remains of each of their consciences has been sublimated to his whims for a decade now

Bad urbanism bluesky tonight, I gotta say.

I don't care how the median American wants to live. I want to not get hit by a car when I bike to work, and I hate that car ownership and sprawl are legally supported if not outright mandated in 10,000 different ways.

women are always saying “lord grant me the confidence of a mediocre man.” ok well he did. now what. is the world a better place? look at what you’ve wrought.

Urbanism—the notion that cities are good, that we should build housing in the dense walkable neighborhoods where people want to live, and that urban governance should prioritize city residents’ quality of life over suburban drivers’ convenience—remains a radical political program in America.

Major announcement in just-posted board documents: DC's Metro is moving fast toward automation. Over 15 years, Metro plans full automation & platform screen doors, which the agency says will improve safety, reliability, & travel times—at reduced costs. www.wmata.com/about/board/...

I feel like the pope being an American cinephile is God finally rewarding Scorsese for a lifetime of devotion

@harvardkennedy.bsky.social and @harvard.edu need to sever ties to Summers immediately

tax the empty (lots)

Beginning to understand why Mamdani's first move is to reform property taxes lmao what is going on

If women are underrepresented in STEM, it's at least partly because men like this offer mentoring, then embarrass themselves by assuming their mentees must be into them, then decide the best solution is to cut ties, which sends the signal to other faculty that the mentee must not be good enough.

One of my recent Penn grads is applying to an aero/astro program at MIT, and I'm pleased to see the program still has a commitment to DEI on their home page. The heavens belong to everyone!

made a similar point on the opinions podcast this week in response to the idea that epstein is a dead end. not only are actual voters interested in this but it divides the gop and puts pressure on the president. it would be political malpractice to treat it as a sideshow

holy father, i'm offering you a chance to skip this boring lunch. get day drunk with jane and i while we watch clips of the '05 world series on youtube

Good news: City Hall bus and bike lanes got striped today despite the best efforts of Jay Young Bad news: the Residence Inn on Juniper has instinctively started using it as valet parking hours after completion. Not camera-enforceable without adding Juniper to the list

At the same time the NY Times was hyping Hillary Clinton's emails, it had a reporter with emails from Jeffrey Epstein that were highly damaging to Trump. The more NYT apologists try to minimize this the clearer it becomes that they don't understand why much of the public doesn't trust legacy media.

Harrisburg has, once again, failed to fund public transit. Agencies like SEPTA are forced to raid their capital funds to run daily service. This is akin to burning pieces of your house in the fireplace to keep warm.

In his budget speech @governor.pa.gov was careful to not say the word 'Philadelphia' once over the 30 minutes, even when talking about next year's 250th anniversary of the US: www.youtube.com/watch?v=xjNN... He's treating Philadelphia as too politically toxic to even mention, let alone defend.

no funding for mass transit and backing out of the regional greenhouse gas initiative. great negotiating, josh!

I'm getting to the point where I'd prefer AOC over most other 2028 contenders. She'd be nearly 39 at inauguration, only 3 years younger than Teddy Roosevelt. And she will have been a US representative for 10 years, only 1 year less than Obama spent in Illinois and US senate.
