Within 3 hours of posting about RSS Readers Nick Bradbury had commented and straightened me out on some FeedDemon configuration information and highlighted some features coming soon for synchronising flags between FeedDemon and NewsGator. Nick is the Architect of these products and founded Bradbury, the company which wrote them before he and  Bradbury became part of Newsgator. This is excellent customer service (and likely due to my addition of Technorati tagging into WordPress using this plugin). The power of blogs and tagging!
Thanks Nick!
