I got the "Oh Crumbs" screen a couple of times today, which apparently shows up when there are database problems. Do you get an automatic alert on those, or should we report them when we seem them? Anyway, consider this the report.
The first time I got the screen, I was trying to post a comment to the blog. I gave up on the comment, but I noticed that someone else's comment went through after refreshing, so maybe it had something to do with two comments being posted at the same time.
The other time I got the screen was trying to read a forum thread, clicking on the New Posts icon. It worked after I hit the back button and tried again.
