If you use the FeedDemon RSS reader for Windows, you should definitely take a look at the first beta of the forthcoming version 2.
As a long-time FD user and currently on the 1.6 beta (version 2 will repalce 1.6), I’ve installed it. Wow! Definitely worth having. More later.
See developer Nick Bradbury’s post for details.
Neville: FeedLounge blows away anything I’ve seen to date. It’s subscription only but if you want to check it out then see Stephen O’Grady’s assessments over at RedMonk. It imported ‘my favourites’ OPML in 2 minutes! Beautifully presented with bags of additional tagging options. I’ll be writing it up early next week.
