Been running my technical knowledge base on Astro for about a year now (ketankhairnar.com). Congrats to the team on the acquisition - here's what stood out from a product/engineering perspective:

Content modeling that actually scales. Built a three-tier system: Concepts (foundational knowledge) → Deep Dives (series-based learning paths) → Systems (production case studies). Each concept tracks prerequisites, related topics, interview relevance by level (L5-L8), and links back to which deep dives use it. Zod validates everything at build time. This isn't a blog template - it's a knowledge graph with static output.

Islands architecture delivers on its promise. React hydrates only for search (Fuse.js across all content types) and a few interactive bits. Rest is zero-JS HTML. Coming from years of Next.js, the bundle size difference is stark. Users on flaky mobile connections notice.

Extensibility without framework lock-in. Wrote a custom Shiki transformer for ASCII diagram highlighting - ERROR renders red, FIX green, DECISION orange. Dynamic OG images generated at build via Satori+Resvg. No Lambda cold starts, no external services, just static assets. Infra cost: basically zero.

View Transitions shipped before others figured it out. One import, smooth page transitions. Small detail, big UX lift.

Where it gets tricky: Complex content relationships require multiple getCollection() calls and manual joins. Works fine, but a query builder would help for sites with heavy cross-linking. Also, the content layer is powerful but documentation assumes simpler use cases.

Product observation: Astro found a real gap - content sites that need occasional interactivity but don't want SPA overhead. Most frameworks optimize for apps and retrofit content. Astro did the opposite and it shows.

Curious how Cloudflare integration plays out. Edge rendering + this content model could be interesting for personalization without sacrificing static performance.
