There are various types of blogs, and each differs in the way content is delivered or written.
By media type
A blog comprising videos is called a vlog, one comprising links is called a linklog, a site containing a portfolio of sketches is called a sketchblog or one comprising photos is called a photoblog.[17] Blogs with shorter posts and mixed media types are called tumblelogs.
An Artlog is a form of art sharing and publishing in the format of a blog, but differentiated by the predominant use of and focus on Art work rather than text.
A rare type of blog hosted on the Gopher Protocol is known as a Phlog
By device
Blogs can also be defined by which type of device is used to compose it. A blog written by a mobile device like a mobile phone or PDA is called a moblog.[18]
Genre
Some blogs focus on a particular subject, such as political blogs, travel blogs, fashion blogs, project blogs, education blogs, niche blogs, classical music blogs, legal blogs (often referred to as a blawgs) or dreamlogs. While not a legitimate type of blog, one used for the sole purpose of spamming is known as a Splog.
Legal status of publishers
A blog can be private, as in most cases, or it can be for business purposes. Blogs, either used internally to enhance the communication and culture in a corporation or externally for marketing, branding or PR purposes are called corporate blogs.
Blog search engines
Several blog search engines are used to search blog contents (also known as the blogosphere), such as Bloglines, BlogScope, and Technorati. Technorati, which is among the most popular blog search engines, provides current information on both popular searches and tags used to categorize blog postings. Research community is working on going beyond simple keyword search, by inventing news ways to navigate through huge amounts of information present in the blogosphere, as demonstrated by projects like BlogScope.
Blogging Communities and Directories
Several online communities exist that connect people to blogs and bloggers to other bloggers, including BlogCatalog and MyBlogLog. A collection of local blogs is sometimes referred to as a Bloghood. http://en.wikipedia.org/wiki/Blog#Types
