It may have been the blogger site itself. Things were lost and removed during a maintenance. My Wednesday post disappeared but they said they hope to restore so maybe your Thursday post will show up. Maybe.
Blogger did it! I was having my first giveaway, announced the winners yesterday and then discovered that Blogger removed posts from yesterday morning! Arrgh - some of my comments for the giveaway ware gone, too. So, maybe next time!
Hope you're enjoying Market!
Yes, it's Blogger's fault. It's been done for a day or two!
