well at least I am trying to move from wordpress.com to wordpress.org… so bear with me if you see stuff wonky…. but just so you have a laugh… this is what I read when I was checking how to export things from wordpress.com to .org. This quote is taken from the wordpress help.
If your blog is hosted here at WordPress.com, we handle all necessary backups. If a very large meteor were to hit all the WordPress.com servers and destroy them beyond repair, all of your data would still be safe and we could have your blog online within a couple of days (after the meteor situation dies down, of course)
You have to give it to them… they are funny!
