In the article at the top, it says that about half of all books read by Americans in 2025 were read by people who read 50 or more books.
So my goal is to be part of that fat tail of the distribution.

Think I was somewhere in the 30s last year assuming my Goodreads kept up reasonably, so it is not at all clear yet if I'll get there.
But, I like a silly excuse to get acquainted with more of my antilibrary.

We all have an "antilibrary." You know, the stack of yet-unread books we might never read. Here is Umberto Eco's wonderful and counterintuitive take on why that unread stack might be as essential for our inner lives as the read www.themarginalian.org/2015/03/24/u...
Umberto Eco’s Antilibrary: Why Unread Books Are More Valuable to Our Lives than Read Ones
How to become an “antischolar” in a culture that treats knowledge as “an ornament that allows us to rise in the pecking order.”

Here's the slide I use when I talk about rising costs in BOTH gas and electricity systems. Capital expended on distribution poles, wires, and pipes is the main cost for utilities and are the main driver of your rapidly growing energy bills. Gas 4X and electricity 2X inflation between 2003 and 2023.

WaPo layoffs are tragic. This, however, is some excellent shade.

Sitting in a Canadian catastrophe conference, and hearing an eerily familiar refrain from what many of us are saying across the border in the US:
"Earthquake insurance penetration rates for homeowners are shockingly low. When the next 'big one' hits, a huge portion of damage will be uninsured."

The western U.S. faces its lowest snowpack on record despite average or above-average rainfall. Warmer temperatures mean more precipitation falls as rain rather than snow, and will worsen droughts in areas like the Pacific Northwest and the Colorado River Basin.

Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/...
And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10....
Paleoclimate evidence generally provides the strongest constraint on high ECS.

I regret to inform you that “1979” by Smashing Pumpkins was released in 1996, which is now 30 years ago. Meaning a similar song released in 2026 would be called “2009”
