So, ScribeFire seems to be putting truckloads of whitespace in my blogger posts. Purportedly this is because ScribeFire's not handling the new Google-owned blogger that well. This seems like a big part of the userbase.
At least the "& nbsp;" stuff didn't show up explicitly this time (I'm posting from ScribeFire for Firefox for Windows, and I posted as a draft first; when I posted from ScribeFire for Firefox for Linux, posting direct, I got explicit nbsp's all over the place. (I like two spaces after my periods, which apparently inserts an nbsp.)
