Ned Batchelder discusses the creation of 'linklint', a Sphinx extension designed to reduce excessive links in documentation. The project developed from a need to address the issue of distracting underlined links and aims to improve documentation clarity by suppressing unnecessary links, particularly redundant references within sections. The extension is currently implemented in CPython documentation, showing significant impact by reducing thousands of excessive links. The author reflects on challenges related to what constitutes an 'obvious' link and the nuances of suppressing links.
