According to Blogger on Twitter, and also as stated on Blogger Buzz, Blogger service was down for some time and in order to remedy the situation, all posts and comments made from 7:37 am PT on Wednesday May 11 through sometime yesterday had to be deleted. According to Blogger buzz, the removal of those posts is temporary and they have started restoring those posts. I trust that they'll follow through.
Interestingly, many posts from the blogspot blogs I follow made it into my RSS feeds and so I am able to read those posts even though they're gone from the blogs. So if you lost a post due to this service problem and you want to repost it, and are too impatient to see if Blogger will indeed restore it to you, I might be able to help you. Of course I can only help you if I subscribe to your blog by RSS feeds, which you'll only know if you ask me! Drop me an email and I'll copy your lost post from my feeds and email it to you. You'll have to reformat it for posting, but at least you can get your clever words back.
