Why the move? Partly it's convenience, but mostly it's due to features and bandwidth. Flickr have more and cooler features than I could ever find time to code, so why bother? I may as well spend my time earning money solving new problems (and displaying JPEGs isn't high on the list of requirements for enterprise application software - at least not in the manufacturing industry). Plus the bandwidth issues make hosting 3000+ photos on the end of my ADSL line somewhat impractical these days - better to leave it to Flickr to take the strain.
So, time to update your bookmarks to http://www.flickr.com/photos/iannelson/ and/or your RSS feeds to http://www.flickr.com/services/feeds/photos_public.gne?id=73512768@N00&format=rss_200 .
