I have this rule when reading blogs.

When I read "well-informed little birdies" or "inside sources" or "people I trust," I replace that with "based on a random email I got from an anonymous source." If I read a lot of these types of statements on a blog, then I stop reading the blog.

This was usually reserved for DailyKOS and other crazy political media, but tech sites are now getting to be bad about it too, especially ones that cover Apple.
