I just bought NetNewsWire. After using the lite version (for free, thanks Brent) I wanted to show my support for the world of shareware. This is only the second piece of software I've purchased like this; Radio was the first.
Update: just got the post function working. Outstanding. I've got an iMac running in our basement, running OS9 and my licensed copy of Radio. I use it as a “server”, allowing me to post from anywhere I can pull up a browser. The best part of NNW's weblog post function is now I don't have to hit the downstairs machine with extra serving work. Posting is *much* faster.
