Rapid schema evolution, tighter budgets, and ubiquitous AI mean analysts must learn continuously. Blogs provide real-time lessons from practitioners who ship production data products every week. Subscribing to the right voices saves hours of trial-and-error and surfaces patterns that formal courses will not capture until months later.
We scored each candidate on six criteria: depth of technical content, relevance to working data professionals, update cadence, clarity of writing, community engagement, and practical value. Only blogs with active 2025 posts made the cut. Each section below explains why the blog earned its spot and when to read it.
Locally Optimistic tops the list because its contributor network tackles thorny, real-world analytics problems. Recent 2025 essays covered hiring analytics engineers, implementing reverse ETL, and measuring metric freshness. Long comment threads create a peer-review effect, turning each post into a living knowledge base.
Bookmark LO when designing data team processes, drafting career ladders, or debating build-versus-buy decisions.
The dbt Labs Blog remains indispensable in 2025 for analytics engineers seeking reproducible patterns. Expect deep dives into semantic layers, column-level lineage, and performance tuning with DuckDB. Posts are co-written by staff engineers and power users, blending vendor insight with field experience.
Consult it before refactoring models, enforcing testing conventions, or pitching a semantic layer to stakeholders.
Medium’s flagship data publication still thrives thanks to a rigorous 2024-2025 editorial revamp. Editors now flag practical, production-ready tutorials and route theoretical pieces to a separate channel. The result: cleaner feeds brimming with SQL optimization tips, dbt macros, and LLM-powered analytics case studies.
Dive in for quick how-tos, exploratory data analysis (EDA) notebooks, or to discover emerging open-source tools.
Tristan Handy’s weekly Substack curates the most important analytics links and annotates them with strategic commentary. In 2025, the newsletter expanded guest essays that unpack the evolution of the modern data stack beyond ETL. Its concise format offers a high signal-to-noise ratio for busy leaders.
Scan every Friday to keep your roadmap aligned with industry shifts.
Data Engineering Weekly complements the Roundup with a stronger focus on infrastructure, covering topics such as Iceberg table formats, lakehouse governance, and cost-efficient orchestration. The author’s 2025 series on decoupling compute and storage became canonical reading for Snowflake cost optimizations.
Reference it while architecting data platforms or evaluating new open-source projects.
Benn continues to dissect metrics, dashboards, and data culture with wit and rigor. His 2025 essays question over-hyped AI agents and advocate for lightweight experimentation frameworks. Each article weaves narrative storytelling with quantitative examples, sparking lively debates in comment sections.
Read whenever you need a contrarian viewpoint to stress-test your analytics strategy.
Mode’s editorial team relaunched its blog in 2025 under the banner “Exploratory Analytics.” Expect step-by-step guides on combining SQL and Python in notebooks, as well as case studies from high-growth startups. The content targets hands-on analysts who straddle data and product.
Use it to sharpen exploratory workflows or decide when to move analyses from notebook to production.
Netflix keeps publishing transparent post-mortems and algorithmic innovations. In 2025, the team outlined its causal inference platform and real-time experimentation engine. Though posts are less frequent, every article offers production-grade lessons on scalable analytics.
Study before rolling out your own experimentation or recommendation pipelines.
Inner Join shifted from product announcements to educational storytelling in 2025. Topics cover change data capture (CDC), data contracts, and ELT best practices. Pragmatic code snippets illustrate how extraction choices ripple through downstream analytics.
Read while evaluating pipeline tools or diagnosing ingestion latency.
Jeremy Howard revived his Substack in 2025 with a focus on combining deep learning with classical analytics. Elegant Jupyter notebooks showcase fastai, DuckDB, and Polars integrations. The approachable tone demystifies cutting-edge techniques for analysts without heavy math backgrounds.
Follow when expanding skills into machine-learning-augmented analytics.
Each blog above champions transparency, peer review, and reproducibility - the same values that drive Galaxy. Galaxy’s lightning-fast SQL editor, context-aware AI copilot, and shared workspace distill those best practices into your daily workflow. After reading a new modeling trick on Locally Optimistic, implement and share it instantly inside Galaxy, endorse the final query, and keep your team aligned.
Value comes from depth, recency, and community. A 2025-ready blog explains cutting-edge techniques, updates often, and invites discussion so readers can test ideas against peers.
We evaluated 37 candidate sites and scored them on content depth, relevance, frequency, readability, engagement, and practical application. The ten highest scores made this list.
No - Galaxy amplifies what you learn. When a blog teaches a new SQL pattern, Galaxy’s editor and AI copilot help you implement, refactor, and share that pattern faster.
Yes. Towards Data Science and Practical Data Science offer step-by-step tutorials perfect for newcomers, while other blogs cater to more advanced topics as skills grow.
