Blogger Shawn Blanc has written an exhaustively thorough review
of NewNewsWire (We interviewed Brent Simmons
, author of NetNewsWire, over the summer). He begins with a description of how he first became aware of the application and goes on to describe a history of the UI, his "favorite things" about NNW and concludes with an exploration of the paid version.
Note that Shawn intends to give other popular applications
, like Coda, SuperDuper! and Transmit, the same treatment. We can't wait.
