David Slifka @davidslifka.bsky.social · 02/10/2026The key is "my situation." My second brain already knows it, so I didn't have to explain anything. That turns "you should check out [x]" from a someday chore to immediately useful. 010
David Slifka @davidslifka.bsky.social · 02/10/2026"Search Tilt Parenting for episodes relevant to my situation. Save those transcripts, and tell me what ideas from each might be useful." It went through the whole archive, picked 29 episodes, saved their transcripts, and wrote me a brief. 110
David Slifka @davidslifka.bsky.social · 02/10/2026ellow parent told me to check out the Tilt Parenting podcast. Great tip. Then I saw 500+ episodes going back ten years. Usually I'd listen to one or two recent episodes at best, then the recommendation quietly dies. So I told my second brain in Claude: 100

David Slifka @davidslifka.bsky.social · 07/08/2026What it doesn't do yet, well or at all: Judgment about what to fund. Supporting organizations with fundraising, connections, etc. Real track records you only get in conversation. The exploratory meeting that turns a half-formed idea into something backable. 110
David Slifka @davidslifka.bsky.social · 07/08/2026What vetting parity looks like: it reads the FEC filings and 990s, researches key people, checks every pitch against 350+ studies, and runs my full evaluation playbook — 86 questions, 51 red and green flags. All the work I'd expect from a human team. 100
David Slifka @davidslifka.bsky.social · 07/08/2026I published a report card for my AI donor advisor. On its core job of vetting organizations, the AI is pretty much as good as a capable human. In other areas, not yet. seeds.bluem.ventures/p/my-ai-dono... 110
David Slifka @davidslifka.bsky.social · 29/07/2026Respect you for raising this. The city-run supermarket idea runs against so much basic economic theory. I’m always openminded to new ideas, but anyone declaring themselves sold without a deep analysis isn’t serious. 030
David Slifka @davidslifka.bsky.social · 23/07/2026Update on my AI donor advisor: ten screening categories, 84 questions, 48 red/green flag items. Plus it has 200+ academic and practitioner research papers for baseline efficacy of tactics under various conditions. All run near-instantly on any project. 010
David Slifka @davidslifka.bsky.social · 21/07/2026I like @adamjentleson.bsky.social's tests for when a group becomes a capital-G "Group": Does it demand positions that are wrong on the merits or lose elections? Sell them with junk polling? Punish the candidates who won't fall in line? Way better than ideology- or vibes-based definitions. 000

David Slifka @davidslifka.bsky.social · 20/07/2026I tested it on an org I chair. I gave a model three pitch docs, turned web search on, and asked 23 diligence questions. AI had an answer for every question; about half the answers held up. 000
David Slifka @davidslifka.bsky.social · 20/07/2026I thought my AI donor advisor was the cool part. But most of the feedback on that piece was some version of "ok, but what should nonprofits do about funders doing this?" Fair. So I wrote that up: seeds.bluem.ventures/p/what-your-... 100

David Slifka @davidslifka.bsky.social · 09/07/2026Organizations fundraising should create a packet of AI-legible materials that they can easily share with funders. I expect this will be common within 1-2 years. 110

David Slifka @davidslifka.bsky.social · 27/06/2026The real magic with AI starts when you give it your own thinking: essays, strategy documents, etc. Then it can start analyzing material *on your own terms* as you would. 000

David Slifka @davidslifka.bsky.social · 22/01/2026Our kids now say things like "I like Alpha 20 times more than my other schools." The future of education will look more like this.

David Slifka @davidslifka.bsky.social · 22/01/2026Alpha School has been controversial for “replacing teachers with AI.” From the inside, this concern is bizarre. The adults at Alpha are just as important and just as present as in other schools. /9 120
David Slifka @davidslifka.bsky.social · 22/01/2026The strongest signal: Of ~20 day-one NYC families, three have already enrolled a second child. The people who've seen it up close are giving the ultimate vote of confidence. 8/ 100
David Slifka @davidslifka.bsky.social · 22/01/2026Prospective parents always ask me what has been bad so far. It’s a very fair question but I struggle for an answer; there’ve been hiccups but nothing that I’d call “bad.” The biggest unknown is whether quality holds as they scale quickly. 7/ 100
David Slifka @davidslifka.bsky.social · 22/01/2026The social concern everyone asks about: There's still lunch, recess, breaks. But the *structured* social learning is great, like town halls where kids debate and vote, group projects, and workshops on interviewing strangers. It's not just screens all day. 6/ 120
David Slifka @davidslifka.bsky.social · 22/01/2026Afternoon workshops teach things I wish I'd learned in school: giving/receiving feedback, public speaking, self-learning (kids had to teach themselves to solve a Rubik's cube). Once you see these skills taught explicitly, it seems crazy that other schools don't. 5/ 100
David Slifka @davidslifka.bsky.social · 22/01/2026What surprised me: How differently Alpha works for each of our twins. Our son thrives on the incentive structures and lack of distractions. Our daughter is filling some learning gaps beyond what regular school would achieve. Both benefit from and enjoy the afternoons and optional homework. 4/ 100
David Slifka @davidslifka.bsky.social · 22/01/2026And homework isn't just optional, it's fundamentally different. No more mystery assignments, no more 3-hour homework nights. Want to skip homework for a family event? Fine. Kid wants to work ahead over break? Also fine. 3/ 100
David Slifka @davidslifka.bsky.social · 22/01/2026At Alpha School, kids finish all academics in the morning using personalized software. Afternoons are for life skills workshops. Homework is optional. It sounds too good to be true; it's not. 2/ 100
David Slifka @davidslifka.bsky.social · 22/01/2026So many parents asked me about Alpha School that I wrote up our experience. Five months in, our whole family (kids and parents) would be crushed to go back to regular school.

David Slifka @davidslifka.bsky.social · 17/01/2026The Politico UATX story hits a nerve because it's the classic authoritarian rise: 1. Make fair critiques of the status quo 2.

David Slifka @davidslifka.bsky.social · 20/11/2025My working model of the country has been that it's split into three groups: Left, Right, and low interest in politics. (And that calling the middle group "moderate" is misleading.) This is a great addition of texture to that middle group. 130
