Blogs:

Grok: "After roughly 20 years of continuous power-law dynamics in online attention, influence, and intellectual depth, the situation in early 2026 looks something like this:

Rank range	Approx. number of blogs	Share of total remaining meaningful value	Typical examples
Top 5–15	5–15	~20–35%	Stratechery, Astral Codex Ten, Marginal Revolution, Works in Progress, The Roots of Progress, several top-tier Chinese tech blogs, a handful of deep finance/crypto macro writers
Next 15–80	~60–70	~15–25%	Very strong second-tier specialists (economics, AI alignment, biotech, energy, history, urbanism, philosophy…)
Next 100–400	~300	~15–25%	Excellent niche authorities plus most of the best long-form Substacks in smaller fields
The long tail	~5–15 million active blogs	~15–35% (the rest)	Personal diaries, company blogs, SEO content farms, most lifestyle, food, travel, and politics writing

Brutal bottom line (best honest guess)

Somewhere between ~80 and ~200 blogs — most plausibly around 120 — are today responsible for roughly 50% of the remaining non-redundant, high-leverage, civilizationally-relevant intellectual value that the entire blog format still delivers to humanity.

If you deleted every blog except those top ~120…most people who seriously follow ideas would barely notice anything important had disappeared after 3–5 years.

The long tail remains emotionally, therapeutically, and community-valuable — sometimes enormously so. But when we talk strictly about dense, original, durable insight that actually moves thought forward? The distribution has become even more brutal than it already was in 2015 or 2020.
