That was quick. I switched back to NetNewsWire after just a few hours with it. Nice and light-weight, hooray Ranchero.
As a plus, because I own a license for NetNewsWire, Ranchero gave me a license for MarsEdit as well. This is my first test of that software.
Update: seemed to work okay. I like the integration with NNW and BBEdit, so I'll probably keep using this.
