🏆 #1 - Top Signal
The Most Popular Blogs of Hacker News in 2025
Score: 74.5/100 | Verdict: SOLID
Source: Hacker News
A 2025 analysis of Hacker News “most popular bloggers” ranks individual-run blogs by HN upvotes, with Simon Willison #1 for the third consecutive year. Willison’s 2025 output exceeded 1,000 posts (118 full-length), and his edge is framed as vendor-neutral, high-signal curation that brings ideas from walled gardens to the open web. Jeff Geerling placed #2 with 10,813 upvotes in an extremely tight race (only 9 upvotes ahead of #3), driven by hardware/self-hosting content and text-first companion posts to YouTube videos. The community highlights that top bloggers are also prolific HN commenters, and the dataset is available as CSV with open CORS—enabling third-party analytics products and tooling.
Key Facts:
- Article title: “The Most Popular Blogs of Hacker News in 2025”; site theme: effective writing for software developers.
- Methodology defines “blogger” as an individual blogger (personal blog) rather than company/team blogs; example: counts John Graham-Cumming’s personal blog but not Cloudflare’s company blog.
- Simon Willison ranked #1 for the third straight year on HN popularity among bloggers.
- Simon Willison wrote 1,000+ posts in 2025; 118 were full-length articles.
- The article attributes Willison’s HN success to vendor-neutral “power user” AI coverage and high-value link/commentary posts that نقل ideas from TikTok/Twitter to the open web.

#2 - Subtle releases ear buds with its noise cancelation models
SOLID | 70.5/100 | Techcrunch
Voice AI startup Subtle launched $199 wireless earbuds (“Voicebuds”) ahead of CES 2026, positioning them as a hardware+subscription bundle for clearer calls and more accurate transcription in noisy environments. The earbuds ship in the U.S. “in the next few months” and include a 1-year subscription to Subtle’s iOS and Mac app for dictation, voice notes, and AI chat across apps. Subtle claims “5x fewer errors” than AirPods Pro 3 paired with OpenAI transcription, and demonstrated whisper-level capture in noise to TechCrunch. The move signals a shift from pure software noise-isolation models toward an end-to-end “voice interface” product category where differentiation may come from wake/lock-screen integration, cross-app dictation, and model+hardware co-design.
Key Facts:
- Title: “Subtle releases ear buds with its noise cancelation models.”
- Source: TechCrunch; Date on prompt context: 2026-01-04; URL provided.
- Subtle is a voice AI startup that builds voice isolation models to help computers understand users in loud environments.
#3 - Neural Networks: Zero to Hero
SOLID | 68.5/100 | Hacker News
Andrej Karpathy’s “Neural Networks: Zero to Hero” is a hands-on course that starts from implementing backpropagation (micrograd) and progresses through character-level language modeling (makemore) to building a GPT-style Transformer from scratch. The syllabus is structured as multiple long-form videos (roughly ~1–2 hours each) emphasizing implementation details, tensor mechanics, and manual backprop to build intuition. Hacker News commenters describe it as unusually effective compared to traditional courses, but also debate practical ROI for most people who will primarily consume foundation models via APIs. The strongest product opportunity is not “another course,” but tooling and guided practice layers (autograd/shape debugging, graded exercises, eval harnesses, and project scaffolds) that convert passive video learning into measurable competence.
Key Facts:
- Source is Hacker News; URL is https://karpathy.ai/zero-to-hero.html
- The course positions language models as an effective way to learn deep learning concepts that transfer to other areas (e.g., computer vision).
- Prerequisites listed: solid Python programming and intro-level math (e.g., derivatives, Gaussian).
📈 Market Pulse
Reaction is broadly positive: “Without looking I knew who was #1,” and multiple commenters emphasize that top bloggers also contribute via thoughtful comments, strengthening community trust. The dataset’s availability (CSV + open CORS) is explicitly called out as something builders can “have all sorts of fun with,” indicating openness to tooling and derivative analyses. There are also operational/data-quality concerns (domain migration aggregation/canonical/301 behavior) raised by a commenter, implying real user pain around identity resolution and attribution.
No community comments were provided in the prompt. Market reaction is therefore best inferred from competitive context: Subtle is explicitly entering an active dictation market (Wispr Flow, Willow, Monolouge, Superwhisper) and differentiating via dedicated hardware + noise isolation + lock-screen wake, implying rising demand for ambient/voice-first interfaces but unclear buyer pull without broader reviews.
