Wouldn't you know that hours after I worry about something happening to my blog, every single post on my blog has lost its line breaks.
How, I have no idea.
Update: Thank goodness I figured out quickly enough that the "Convert Line Break" setting for my blog had been toggled. I still have no idea how.
Meanwhile, please enjoy this hysterical rendition of Torn by Natalie Imbruglia, as acted out by comedian David Armand ... and Natalie Imbruglia.
