A Blog (aka “Web log” or “Weblog”) is an online diary where a person, organization, or company records actions, opinions, and beliefs. Some blogs filter news from internet sources and add brief remarks and links. Other blogs have original content. Several blogs enable readers to comment and connect with the publisher. “Blogging” means writing blog posts. Many blogs include photographs, music, and videos (“Vlogs”). Blogs form the “blogosphere” online.
