I think we're all having problems. Blogger was down for quite a while last night. I've noticed other people's posts disappearing also.
My post did not disappear but when I tried to post it took me to blogger page and they said they removed posts and they were working to get everything back to normal. I couldn't figure out either what was going on.
I have so many friends who have complained about this in the last week. Some of them got their posts back but many did not. How frustrating :(*~*~*
