There appears to be some confusion on the difference between forum / discussions and blogs. In general, a forum/discussion is intended for two way conversations and/or questions and a blog can be thought of as more of a one way journal that can be commented on.

A blog (short for weblog) is a personal online journal that is frequently updated and intended for general public consumption. They are usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Blogs are defined by their format: a series of entries posted to a single page in reverse-chronological order. Blogs generally represent the personality of the author or reflect the purpose of the Web site that hosts the blog. Topics sometimes include brief philosophical musings, commentary on Internet and other social issues, and links to other sites the author favors, especially those that support a point being made on a post. The author of a blog is often referred to as a blogger.

Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketches (sketchblog), videos (vlog), music (MP3 blog), audio (podcasting), which are part of a wider network of social media. Micro-blogging is another type of blogging, one which consists of blogs with very short posts.
