Comment on Newsfire

Have you tried this free version of NewsfIre? If you did, you probably have noticed that you cannot delete David Watanabe's blog RSS feed. That's the main reason why I sent it to the trash.
But there's more... Vienna and NetNewsWire are now both free. (Vienna has always been free.) And, IMHO, they're both better than NewsFire. They both have better (and nicer) interfaces, they are both easier to customize and both have built-in browsers (NewsFire has not).
Just one more thing... When NetNewsWire went free, NewsGator refunded the users who had bought a licence on the latest months. Why didn't the developer of NewsFire do just the same?
