Glenn’s commentary on Mozart (How Mozart Became a Bad Composer) is inspiring, even beyond its musical context. Glenn is an original thinker—eloquent and masterful—yet he didn’t spend a single moment making his audience’s experience easier. The speed of his thoughts, the density of his information, and the impromptu free flow of his words were mesmerizing, even as he buried his argument beneath layers of complex ideas. Though Glenn seemed to critique Mozart harshly, beneath the surface of his sharp words and seemingly scathing remarks lay a deep respect for Mozart’s genius....

The famous Bach interpreter Glenn Gould (who is considered as among the most famous and celebrated pianists of the 20th century), famously commented negatively on Mozart. In 1968, Gould presented a segment of the weekly public television series Public Broadcast Library. His topic was “How Mozart Became a Bad Composer.” (source: OpenCulture) Glenn monologued a 40min critical masterclass, accompanied by a piano—filled by piano snippets dissecting Mozart to the core, and Glenn’s sparkling satrical humor....

Linfeng visited SUFE to give a talk on his job market paper “Crowdsourcing Digital Public Goods | A Field Experiment on Metadata Contributions”. He interviewed for School of Computing and Artificial Intelligence though I think he is more of an economist. Abstract This study explores why people choose to contribute metadata, which is data about data. Using a field experiment conducted with more than 3,000 authors of AEA journal articles, our control message reduces the uncertainty about the future value of metadata, whereas those from the treatment conditions additionally make the private or social benefits of metadata salient....

Following the blog about Birdwatch’s mechanism design, here’s some latest news about it: Community Notes, formerly known as Birdwatch, is a feature on X (formerly Twitter) where contributors can add context such as fact-checks under a post, image or video. It is a community-driven content moderation program, intended to provide helpful and informative context, based on a crowd-sourced system. Notes are applied to potentially misleading content by a bridging algorithm not based on majority rule, but instead agreement from users on different sides of the political spectrum....

Here’s an interesting paper about crowdsourcing annotation of tweets. Given a twitter post containing possibly misleading information, the Birdwatch project aims to crowdsource comments on the OG tweet. One problem is to choose among the annotations one most credible annotation to display. Birdwatch: Crowd Wisdom and Bridging Algorithms can Inform Understanding and Reduce the Spread of Misinformation Stefan Wojcik et al. Arxiv link. Background So, about Birdwatch: Birdwatch is Twitter’s community-driven approach to identify misinformation....

The Pavane in F-sharp minor, Op. 50, is a short work by the French composer Gabriel Fauré written in 1887. It was originally a piano piece, but is better known in Fauré’s version for orchestra and optional chorus (Wikipedia). It’s so popular that it has multiple main-stream versions: an OG piano version, a choral version (here), (and of course) adapted ballet, and a most widely played orchestra version. The piece began with a expressive, almost-conversational flute solo....

My paper “Price Stability and Improved Buyer Utility with Presentation Design: A Theoretical Study of The Amazon Buy Box” has been accepted to The Web Conference 2025 as a poster presentation. The paper’s reviews are available here on openreview. Many thanks to all the comments, advice and discussions. See you soon with the camera-ready version and poster will be prepared and released soon ;D

Tokyo feels like a more mature, perfected, and upgraded version of Shanghai. Having visited all the major hubs, I can confidently say that Tokyo stands as the most modern, connected, and meticulously managed metropolis on the planet. What sets Tokyo apart is how well it’s developed and managed from the bottom to the top. While I can’t claim to have seen every layer of this vast system, my experience and observations reveal a city engineered to perfection....

I could go on about how social media has revolutionized business models in the hyperconnected age. When there are seemingly infinite exposures online, even a 0.01% yield rate can turn a million views into thousands of sales. So now, popularity often correlates with quality, but the cause-n-effect interplay is meddled by the algorithm’s invisible hand. For one, algorithms amplify what’s already popular—so now, people drive past Izu-shi’s most splendid costal line in Japan—forget about the mountains, sunrise in private onsens by the sea—to cluster in Izu Saboten Zoo to see Capybara Outdoor bath:...

Nara is a charming city that, in some ways, reminds me of Palo Alto—if you replaced Stanford with its famous Deer Park—while Nara does have a few auxiliary industries, its heart undeniably beats for tourism. Deers are considered sacred messengers of the gods in local Shinto tradition. See more about Nara deer here at Nara’s official site. And the undisputed stars of the show are the deers. The city has developed an impressively thoughtful system to ensure the well-being of its deer....
