## Personal Blogs Are Back — Focus Now on Niche Blogs
**Article:** [Read Full Analysis](https://disassociated.com/personal-blogs-back-niche-blogs-next/)
**HN:** [Discussion](https://news.ycombinator.com/item?id=46009894) — **581 points**, 349 comments
### Revival Trends
- Personal blogging rising, driven by:
- Disillusionment with social media.
- IndieWeb/SmallWeb ethos: independent writing, authentic connections.
- Author’s thesis: revival is incomplete without **domain-specific niche blogs** producing trustworthy, in-depth content.
### Best Practices for Authors
1. **Write to Learn** — Teaching concepts clarifies your own understanding.
2. **Show & Tell in Job Hunting** — Even a small personal blog signals initiative & communication skills.
3. **Maintain for Self-Reflection** — Tagging systems help trace your knowledge growth.
4. **Value Reader Quality Over Quantity** — Engaging one influential reader can outweigh casual traffic.
5. **Express Authentic Passion** — Avoid overly utilitarian resume-padding tone.

## Agent Design Challenges (Armin Ronacher)
**Article:** [Read Post](https://lucumr.pocoo.org/2025/11/21/agents-are-hard/)
**HN:** [Discussion](https://news.ycombinator.com/item?id=46013935) — **332 points**, 190 comments
### Lessons Learned
- **SDK Choice:** Prefer native SDKs (OpenAI, Anthropic) over abstraction layers like Vercel AI SDK for full control.
- **Cache Management:** Explicit control in Anthropic allows cost efficiency and complex operations:
- Place cache points at critical contexts.
- Avoid cache invalidation unless necessary.
- **Task Loop Optimization:**
- Repeat goals/failures to reinforce agent focus.
- Run iterative tasks via sub-agents to isolate failures.
- **Shared State:** File-system abstraction remains a practical backbone for multi-agent workflows.
### Strategic Advice
- Avoid chasing immature tech paradigms.
- Wait until innovations stabilize before adoption.
- Recognize that many frameworks (e.g., LangChain) may be obsolete with newer LLM capabilities.
