Well, that sucks.  Comments have disappeared.  I think they're gone for good.  I exported them, but Blogger isn't cool enough to let me import them, so now I have a really technical-looking file full of comments, without the blogs that went with them.  Oh well.  You said nice things.  Maybe one day they'll let me import them...
More to come on the insecurity topic.  I've been busy with template changes and trying to figure out how to NOT have to pay for comments.
