A digital garden is a concept for publishing personal knowledge on the web that diverges from the traditional personal blog format. Instead of presenting polished articles in reverse chronological order, a digital garden is more akin to a work-in-progress wiki, featuring a collection of evolving ideas. These ideas are not organized strictly by publication date but are linked through contextual associations and are inherently exploratory. The ethos of digital gardening emphasizes continuous growth and evolution of content, embracing imperfection and the process of learning in public.

Maggie Appleton has a great overview of the history and ethos of digital gardens.
