Yes, I believe it can be. But usually a blog is a website that compiles news from other websites and means of media to give the reader an extensive insight on the news of certain subject, i.e. Twilight, you have HisGoldenEyes.com, TwilightLexicon.com; Harry Potter, you have TheLeakyCauldron.com, etc

All of These.
Blogs usually confine themselves to the opinions of the person blogging. If you find a reliable blog, you should continue checking it. Someone writing a blog can put anything they want on it. Some bloggers try to put informational blogs on the site for reading by interested persons. In addition: To determine if a blog is reliable, don't depend only on the information from the blog. Check other resources. Most blogs are the opinion of the blog owner/writer and may not always be reliable.

To determine if a resource might be useful, you will need to evaluate the information in the resource and decide if it is valid, useful, accurate, reliable, and relevant. You should also check the date of publication.
My view is that metro-editi is not reliable. The page which slammed Snopes as a bias, unworthy source of information is full of right-wing blather. It sounds almost like a FOX "noise" blog

Information on Numark DJ can be found from many different online resources. The most reliable resource is the official Numark website, which has detailed information about Numark DJ.
