Owl Post, Oh wait - "Blog" Post

I just finished watching HP PoA again for the tenth time and it struck a chord, parallel. Our blog posts are much like the Owl Posts in Harry's world. We put out our message and set it free. Then when you happen by, it's waiting for you to read. Just give Hedwig or Pigwidgeon a snack and a reply and they'll be on their way back to Harry or Ron or even Snuffles.
