Tried it yet again, and followed customization instructions on the website... which haven't really been updated in a while. It still fails to connect to any of my Blogger API sites always failing with a 405 error. This may be changes to the blogger API by Google, but I have not time to do debugging for the developer. This make about 2+years of trying this software with the same result. That being said, I'm in no position to rate subentries (Features, etc.) for this software. And how unfortunate that MarsEdit is the only other "similar" option listed here, since its editing interface has changed little in years and is still a decade behind the times in the bigger world beyond macware.
ADDENDUM: Okay, since MacUpdate is forcing me to do subratings in order to post this, guess I'll just have to give 2s across the board.
