A blog is a type of dynamic site in the way that it is developed, but it is geared toward a specific function. Think of it as an online diary. A place for you to express yourself on whatever subject you please. Blogs also typically have certain features built into them that help keep track of cross-linking with other sites (trackbacks and pingbacks).
Like other dynamic sites, they may have a web-based administration page to allow you to maintain your content. Some blog systems even allow you to make new posts via email or your mobile phone.
This site is built on a blog platform called WordPress. It’s very widely used, and like other Open Source products it is 100% FREE.
