Inflation-adjusted median income has more than doubled since 2000, and is up 44% since 2017. The Black population, which had risen from 2000-2017, has now dropped below 2000 levels.
A map of Washington D.C. showing neighborhood change between 2017 and 2023 in the Anacostia neighborhood south of the Anacostia River. The census tracts to the northeast, near Capitol Hill, have had little change; the substantial change, up to a loss of 16.6%, is in the southwestern part of the neighborhood, near the bridge to Alexandria, Virginia

Go Bears. #bike4california
At a BART station platform,two bicycles lean against a wall. A smiling woman in a gold jacket holds up a blue and gold flag attached to one of the bikes. The flag depicts a bear riding a bicycle towing a trailer with the script California logo of the California Golden Bears.

Lack of human structures?
A desert landscape. In the foreground is an apparently dead juniper bush; other juniper bushes dot a red rock bowl. A small depression holds water reflecting the blue sky. On the far horizon, mountains with some snow are seen.

A cartoon of Homer Simpson holding up a jeans jacket with "DISCO STU" in rhinestones on the back. Marge looks at it skeptically.

The SF Chronicle can't really hope to have an opinion writer as bad as Ross Douthat, but they try.

Looks like this thing needs a modification.

Great to see you out there!
A group of people stand on a stage in front of a lake, and a sign reading "NO TROOPS IN OAKLAND." The podium has a sign reading "YES ON PROP 50". The speaker is a black woman looking at her notes. On the left, someone in a black shirt facing the crowd raises a fist. Next to that is a smiling person in a pink skirt and jacket with a yellow shirt and a sun hat, holding a sign that looks like a NO PARKING sign but reads NO KING. A person in a black tshirt crosses his arms. Up on the stage, a person in a yellow top appears to be MC'ing the vent. On the right of the podium is an ASL interpreter moving his hands. Several other people stand in a cluster on the right of the image.

So helpful of Insta to break web notifications so you can't see which post people are responding to.
Screenshot of an Instagram notifications panel, showing a number of different people (names redacted), liking apparently multiple different posts, but with no information about which posts they are.

An apparent city park at night, with a grassy field lit by pathway lights. A large group of people with decorated bicycles are standing around the perimiter. Someone appears to be fixing a flat on the right side of the image.

Gotta say, that's a really odd set of business for G to highlight.
A screenshot of Google Maps from an unnamed location. A blue line representing directions enters along the waterfront from the north and turns to the east, apparently uphill. A number of points of interest are highlighted, including "Lavender Bakery & Cafe", "Sprouts Farmer's Market", "La Marcha Tapas Bar," "Waterside Workshops (recently viewed)", "Green Living Builders, LLC", and "The Sperm Bank of California."

The Lange image is apparently shot from 8th Street, and the building is gone. But, on Franklin, one of the original ornamented pillars remains. It would have been at the back of the building from her vantage point.

This wasn't very long ago.
Black and white image of a storefront. A 1940s-era car is parked in front. The store has a sign, "GROCERY WANTO: Fruits and vegetables". In front of the windows, in bold capital letters, is a new sign reading "I AM AN AMERICAN." (A famous image from Dorothea Lange). Black and white picture of the front of an apartment building; the main feature is a metal roll-up grate to a parking garage. The building is concrete and fairly modern, perhaps from the 1970s. To its left is an older brick building, with one ornamented pillar next to the modern building.

A selfie of a smiling man in front of an abstract modernist sculpture, curves and swoops painted in green. Students of early funk will recognize it as the sculpture the band posed on on the cover of Sly and the Family Stone’s “Dance to the Music”

I put together a RWGPS Collection of all of my Bay Area Bike Rides routes. 2300km, 35470m of climbing in aggregate. A challenge?

A map of the San Francisco Bay Area, with many routes displayed, stretching from Petaluma in the north to San Jose in the south. The highest density is in the East Bay near Berkeley.

@ebbp.bsky.social April 2025, Spots vs. Stripes playlist:

open.spotify.com/playlist/0vs...

Hits were Yerba Buena, White Stripes, Sly and the Family Stone, De La Soul, Rebirth Brass Band, Queen, and Human League (karaoke zone, best in set!)
A moon seen at night through altocumulus clouds shines over a group of people standing with bicycles. Many of the bikes have bright wheel lights in different colors. There are several trees within the group; the area looks like a park of some kind.

Hey @bikeeastbay.bsky.social @walkoakbikeoak.bsky.social, can we at least get a convex mirror here? Jingletown, East 7th at 29th, blind corner at a freeway entrance. It's an important connector.
Two cyclists ride in a crosswalk in an industrial area. One is gesturing with her right hand, apparently at a car to her right. Both are looking to the right; other cars are turning right from the facing street.

Here's Garry Tan talking about building a technofascist state, and how "if it works in SF, it will work anywhere".
www.youtube.com/watch?v=24YF...

And here's the new "Black Action Alliance" supporting Taylor, which happens to have the same San Rafael address as Tan's GrowSF. Also, no Black people.
Retweet from Emily Mills: "Same address as Grow SF and Neighbors for A Better San Francisco and Govern for California. (Seems like Nielsen Merksamer is a go to for some people.)" Retweeting Oaklanders Against Loren Taylor for Mayor: "New astroturf group just launched. “Black Action Alliance” which claims to be Black Oaklanders but they have a San Rafael address."

Of course the house with literal astroturf also has a Taylor for Mayor sign. #oakland #empowerfascism
In the foreground, a political lawn sign reading "Loren Taylor for Oakland Mayor: Solutions over Slogans". In the background, a front yard area covered by astroturf.

With the Great Highway extension narrowed for construction, and with the permanent road closure from Sloat to Lincoln about to start, I modified the routes on bayareabikerides.net which begin at Daly City BART to go through Park Merced instead of down John Daly to the lake. #ridebike
Two bicyclists in yellow windbreakers ride towards the camera, on a wide road near a beach. They appear to be relaxed because no cars are allowed. The day is cloudy but they are smiling.

Picture of a crowd in a parking lot at night; at the center of the image is a custom wooden bike trailer holding a sound system lit with blue and yellow LED strips and disco lights. In the background are a number of people in costumes standing talking to each other, along with bicycles, one decorated with bright turquoise lights.

Some good fresh rock cuts out on Trestle Glen @geology.bsky.social
A large excavator is scraping dirt from a steep hillside, adjacent to a house perched on the hillside. It appears to be a project to construct a new house. The dirt and rocks are all shades of brown, with a large boulder sitting in the foreground to the left of the image, opposite the excavator. The hillside the excavator is scraping at is displaying layers of rock, probably sedimentary, several inches thick.

An event flyer titled "Ride 4 Mayor!", 12/9/24. Rideout from Rich City Gallery 4PM. Cycling adocate and Rich City homie will be installed as new Mayor of Albany! The image is a duotone picture of a man wearing a helmet and a mask, along with a camera chest strap, standing behind a custom bike with "Rich City Rides" stickers on the top and down tubes.

Those who ride Pinehurst: I've just noticed that the bike path from School Street to the Canyon bridge is now open as an alternative to Moraga Way/Moraga Road. Not bad (probably lots of walkers on weekends).

I've updated the route on Bay Area Bike Rides.

bayareabikerides.net/moraga-pineh...
A narrow wooden bridge crosses a gorge with autumnal trees. The bridge appears to have been constructed recently; it has high railings with six safety cables strung along its length. The bridge is wide enough for one bicyclist but probably not two. On the far side it appears the trail turns; a wooden fence can be seen in front of the roof of a house.
