FRIEND BLOG
A FriendBlog is a distributed networked journal on the web, composed of short, frequently updated posts written by friends connected through their similar interests. The author allows his FriendBlog to connect to other FriendBlogs, belonging to friends and acquaintances. This creates a "chain" of blogs.
MEDIA BLOG
Some blogs serve as media watchdogs, reporting on falsehoods or inconsistencies that are presented as facts in the mass media. Many media blogs are focused exclusively on one newspaper or television network.
RELIGIOUS BLOG
Some blogs discuss religious topics. Religious blogs show the public's points of view on various controversies both in religion and in politics, economics, and life in general.
FORMATS BLOG
Some weblogs specialise in particular forms of presentation, such as images (see web comics), or videos (see videoblog), or on a particular theme, and acronyms have been developed for some of these, such as moblogs (for "mobile" blog).
VIDEO BLOG
In January 2005 the first VloggerCon was held, catering for a new breed of bloggers, the video blogger. A vlog, or videoblog, is a blog where video is included in blog posts. This is also known as videoblogging.
