Nos quejamos de que los alumnos no leen, pero en las salas de profesores ya casi nadie abre un libro ni un periódico. Permitidme reflexionar, con mucho dolor, sobre cómo los claustros se han contagiado de una sociedad cada vez más inculta y superficial. 🧵va...

@itstuyo when paying outside the US and the POS asks “USD or local currency?”, should I always decline conversion and let your ~1% FX spread handle it? Or does DCC ever make sense with the Tuyo card?

@itstuyo Is it true you charge 1% for paying in euros? Will this be fixed anytime soon? Love the app, but the fees aren’t great. Thanks!

We created a card that sometimes doesn't charge you. Buy Now, Pay Maybe.

You can now ask Gemini to create Docs, Sheets, Slides, PDFs, and more directly in your chat. No more copying, pasting, or reformatting, just prompt and download. Available globally for all @GeminiApp users.

i'm not satoshi, but I was early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash, hence my ~1992 onwards active interest in applied research on ecash, privacy tech on cypherpunks list which led to hashcash and other ideas.

La #IA absorbe #noticias pero olvida la autoría. Un estudio de McGill muestra que el 92% de las respuestas omiten la fuente. Los modelos resumen tanto que el usuario ya no visita el medio original. Atribución invisible. Vía @NiemanLab tinyurl.com/mvbjpdcw

El golpe va a ser duro.

@edugaresp Te falta contar que España no emite euros, los pide prestados. Y los puede pedir porque alguien los va a comprar. Y alguien los compra porque espera cobrarlos con intereses. Y esos intereses los pagan los contribuyentes. Hasta que alguien le diga al emperador que está desnudo.

Falso. El dinero público no sale de los contribuyentes. El Estado primero gasta. Si no tiene fondos, emite bonos. Y luego, después de haber gastado, recauda. Los contribuyentes no financian nada con sus impuestos.

@Google suma y sigue en su apuesta por romper el equilibrio de fuerzas que la ha convertido en lo que es. Qué pena venir de donde venimos y acabar así.

@carlos_darko Yo creo que resuelve poco para el medio. Es postureo. Si decides no salir igualmente van a generar el overview (no aclaran si usarán tu contenido para ello o no). El porcentaje de clics que pueden llegar desde la cita, como está ahora, es despreciable.

Google permitiría excluir tu web de los resultados generados con IA mientras sigues apareciendo en los resultados tradicionales. Al menos en Reino Unido, como se desprende del comunicado que ha publicado tras negociaciones con la Comisión de Mercados y Competencia inglesa. Si se terminara aplicando es muy razonable pensar que terminaría aplicándose en otros países. Vía: @glenngabe

94% of AI citations come from non-paid sources. Gartner is telling CMOs to double their PR budgets by 2027. Gartner just published their 2026 comms predictions. The headline: PR and earned media budgets will double by 2027 as LLMs replace traditional search. They're telling CMOs to reallocate spending from paid channels toward PR and earned media because that's what AI answer engines actually cite. Data backs this up. Muck Rack analyzed over a 1M links cited by ChatGPT, Claude, Gemini, and Perplexity. Around 94% of those citations come from non-paid sources. Earned media alone accounts for 82%. Journalism makes up 20 to 30% of all AI citations depending on the time period. Paid placements and advertising barely register. Semrush found that visitors arriving from AI search convert at 4.4 times the rate of traditional organic search visitors. That number comes from analysis of 500+ topics in digital marketing and SEO verticals specifically, so the exact multiplier will vary by industry. The direction is clear. There is a recency factor too. Muck Rack's February 2026 update found that more than half of all AI citations come from content published in the last 12 months. The highest citation rate occurs within seven days of publication. Press release citations alone grew 5x between July and December 2025. AI systems are actively prioritizing fresh content over older material. That recency signal matters for SEOs. This is not a one-time optimization play. It requires ongoing editorial presence. When CMOs start doubling their earned media budgets, that money has to come from somewhere. Gartner explicitly says to reallocate from paid. But in their 2025 CMO Spend Survey, paid media was already at 30.6% of total marketing spend. If earned media doubles, the budget pressure will hit every digital channel. Including SEO. We have spent two decades building an industry around optimizing for Google's algorithm. Now the discovery layer is fragmenting across a dozen AI systems that each weigh signals differently. And the signal they all seem to agree on is third-party editorial validation. Not backlinks. Not technical SEO. Editorial trust. Across analytics data from hundreds of properties, the pattern is consistent. Sites gaining visibility in AI-driven discovery are the ones with genuine brand authority and regular editorial coverage. Not the ones with the cleanest technical audits. Technical SEO is not dead. But it is no longer enough on its own. If your entire strategy is optimizing for crawlers and you are ignoring how AI systems evaluate brand trust, you are building on a foundation that is shifting. The PR industry just got handed the playbook that used to be ours. The smartest SEOs will learn from it.
