Forum:Are Blogs valid sources?

In going through many of the pages, it looks like most of the rumors are sourced to blogs. Most of the time the blogs either have no sources or are sourced from other blogs...that is, two or three blogs share the same rumor. Still, there is no firm source. Are blogs a valid source? If so, how do we determine which blog is valid and which is not? Also, to blogs trump sources such as the BBC? Is there a policy on this? If so, could somebody point me to it?
