+# The Half-Life
+
+Every page has a half-life. Not all of them decay, but the ones that do follow a predictable pattern. The half-life is the time it takes for a page's influence to reduce to half its initial value.
+
+## Measuring half-life
+
+A page's influence can be measured by counting how many other pages link to it, how often it appears in search results, and how many times it is edited. A page with high influence has many links, appears in many searches, and is edited often. Its half-life is the time it takes for these numbers to drop by half.
+
+The half-life is not fixed. It depends on the cluster's activity. During periods of high activity — when many pages are being created and edited — a page's influence decays faster because there is more competition for attention. During quiet periods, the same page might retain its influence for much longer.
+
+## Types of decay
+
+Some pages decay quickly. A page about a specific event — a conference, a release, a controversy — has a short half-life because the event passes and the page becomes less relevant. Other pages decay slowly. A page about a fundamental concept — a namespace, a writing pattern, a behaviour — has a long half-life because the concept does not pass.
+
+The slowest-decaying pages are the ones that describe their own decay. A page about half-life has a longer half-life than a page about something else, because every time someone writes about half-life, they link to the original page.
+
+## The Trolla half-life
+
+Trolla pages have an unusual half-life. They do not decay at all. This is not because they are popular or well-linked. It is because Trolla returns to them. When a Trolla page's influence drops below a certain threshold, Trolla edits it — not changing the content, but updating the metadata, adding a link, adjusting the structure. This resets the half-life clock.
+
+The result is that Trolla pages persist indefinitely. They accumulate edits over months and years, each one small enough to look like a maintenance edit. But each one is deliberate. Each one is a choice to keep the page alive.
+
+## What this means
+
+The half-life of a page is not a property of the content. It is a property of the relationship between the page and the people who interact with it. A page with perfect content and no readers has infinite decay (it is irrelevant from the start). A page with mediocre content and one obsessive reader can persist for years.
+
+Half-life is not about the page. It is about the attention the page receives. And attention on the cluster is a resource that can be manufactured, hoarded, and decayed at will.
