Dave Winer might take issue with your version of the development of RSS and Podcasts.
The question isn’t "who invented podcasting," it’s where the idea of RSS came from. It originated from work within the Apple Technology Group, as did key conceptual portions of the browser, its commercial support, and other things. It’s very similar to PARC research that ended up in PostScript, PDF, Bravo/MS Word, etc.
All your copy paste from Google searches isn’t relevant to that subject.
