I've upgraded all of the RSS feeds on this site to RSS 2.0 format. I've done this because I had a few comments that my posts were doubling up in some news aggregators after I edited a post after publishing it.
Talking of news aggregators, I've been using the beta version of Nick Bradbury's FeedDemon, which even at this stage, looks like being as rounded and phenomenal a product as his TopStyle CSS editor. Nick reminds us of how great traditional Windows desktop applications can be. If I still had the time to develop applications using Delphi then I'd aspire to emulate what Nick does.
