I'm rewriting this post.
Every other post I've written over the past 3-5 days has had problems with lost line breaks. All my text runs together. It's as though Blogger had broken their age-old management of paragraph breaks. I've tried Safari 3, Firefox 3, ScribeFire, XP, OSX, Blogger-standard and Blogger-in-Draft.
My original post implied the problem was with ScribeFire, Blogger in Draft, and Firefox 3. Then I thought it was Firefox 3 and any version of Blogger. Now I think it's any version of Blogger with Firefox 3 and Blogger-in-Draft with Safari 3.
Basically Blogger is having a really lousy holiday weekend.
They'll fix this eventually. It's not hard to spot!
