Here is the latest from Blogger Buzz:
Update (5/14 5:37 PM PST): We're making progress restoring comments, some blogs with a lot of content are taking a little more time. Thanks for bearing with us.
Update (5/13 7:46PM PST): Nearly all posts since Wednesday are restored, now bringing back comments from last couple days. We expect the comments to be back this weekend or sooner.-Blogger Is Back
No new updates or word on whether we should still wait for our posts to be restored. I will therefore begin to attempt restoring the posts myself if it doesn't happen very soon.
Since I haven't written a News and Notes in a while, and have much more to say, for now, I'm calling this "part one". I'm optimistic that there will be a "part two", about as optimistic as I am that Blogger will ever restore our lost posts.
