Recently I've been doing more podcasts, and finally not cringing when I hear my deep voice. Me and Tom Morris have started a podcast in the vain of the pretty dead Gillmor Gang. The MP3 file is on Archive.org and you can subscribe to the feed here.
Between all the outages and bad quality of my voice, there is a pretty good discussion about a whole host of things including RDF/A vs Microformats, XHTML vs HTML5, the semantic web vs The Semantic Web. Tom is working on some clever notes system which I assume uses RDF or OPML to clever effect.
