What did Dave Winer popularize for audio syndication?

Answer

Use of the RSS enclosure tag

Dave Winer is identified as a key figure whose work standardized the blueprint for software to automatically handle serialized audio content. His specific contribution involved popularizing the use of the RSS enclosure tag. This tag was crucial because it allowed developers to embed a direct hyperlink to a separate media file, specifically an MP3 audio file, directly within the otherwise text-based RSS feed structure. This mechanism provided the necessary machine-readable specification for programs to identify, download, and manage content sequentially, forming the distribution standard upon which podcasting was built.
