Relaible sources 
In hopes of stopping the attempted diminuation of internet only news sites, AKA blogs, that has persisted though the Huffington Post was sold for 300 million to AOL, and Bob Keller's insulting regard for the Huff Post was thoroughly smacked down and made to look silly and ignorant by Arianna Huffington in reply, here is the relevant WP on internet only news sources. Blogs" in this context refers to personal and group blogs. Some news outlets host interactive columns they call blogs, and these may be acceptable as sources so long as the writers are professional journalists or are professionals in the field on which they write and the blog is subject to the news outlet's full editorial control. BTW, The Raw Story has 3 million uniques and a full on professional staff. Since we are citing republican sock puppets like Fox News and The Washington Examiner, idealogical objections to Raw Story seem selective and situational.
