If I may just add to that, as a very specific example within the regulations now for “publicly available”, one of the categories talks about how if it's “published”, and it gives examples of being published in a newspaper or a magazine or things like that.
We've had several interpretations out of various privacy commissioners' offices across the country that say you can publish a blog every day and have 50,000 readers, but that anything you publish on that blog does not count as being publicly available for the purpose of the regulation. I think, in fact, there's room within that wording to say that “published” includes a blog.
