Right now, I'm testing NetNewsWire together with b2, but it doesn't look too sexy. Especially the category stuff doesn't seem to work. I wish I would be able to select the category manually, and enter the title into NetNewsWire's title field, and not the body. But well, I have to dig a bit more into b2's XML-RPC interface, then I will probably find out which weblog type I have to configure in NetNewsWire, since b2 isn't supported natively.
