Abel's presentation on Web 2.0 was the most popular presentation of the STC 2007 conference (at least this is my impression from these interviews). In his presentation, Abel touches upon RSS feeds, wikis, blogs, geospatial positioning, social networking, tagging, podcasts, and other Web 2.0 technologies. He expands here on geospatial positioning and tagging. Abel also explains why he uses a newsletter in addition to a feed for his popular blog, www.thecontentwrangler.com.
