About this data

This page monitors the linguistic simplicity of descriptions within open-source project README files as they evolve. We measure this using the Flesch-Kincaid Grade Level, a widely recognised metric for text readability.

By analysing the average grade level and its variation, we aim to identify trends in how developers communicate their projects' value and technical intricacies. This could reflect shifts in target audiences, evolving communication standards within the open-source community, or changes in how project information is presented.

Why this isn't published anywhere else

The search results show tools and research related to readability and 'drift' in code and documentation, but none specifically track the linguistic simplicity score drift of open-source project READMEs over time.

Uniqueness score 1.00 — assessed against live web search results when this subject was created.
