and... we're back
But Blogger users check this out: while re-editing my template multiple times today, I ran into the SAME ISSUE I had that tanked things. Occasionally, when visiting the Template edit page, without notice, the template only partially loads. It seems to randomly cut off... you can scroll to the bottom of the edit window to discover it... like it falls off a cliff. If you unsuspectingly hit "Save Template" at this point, you've tanked your blog.
Google is my hero (I plan to blog about that more soon), but I hope they'll check on this soon... it's enough to make me start looking at other blog homes today.
