I use Kung-Log to edit Reactuate. I use NetNewsWire Lite to read news. I never got the full NNW version because I didn’t want the editor. I tried it for awhile, but didn’t like it.
So now I’m trying out the new beta of MarsEdit, which is a rewritten editor from the NNW people. So far it pretty much does everything Kung-Log did, though sometimes in a different way.
I can’t figure out how to add a keyboard shortcut to the custom tags, but it is probably there. And I need to mess with the iTunes insertion script to get it to format the way I want.
