Blog: Think of blogs as journal entries which allow commenting. Blogs are typically unvarnished thoughts, tips, general information, ideas and opinions. Blogs are generally between 100 and 500 words with comment responses being very brief typically thanking the posting party for their assistance.

Forum: Think of forums as an individual (or group) looking for feedback on a specific question or topic. Discussion forums typically require a membership and often consist of like minded individuals. Forums often allow notices of new posts to be emailed to all members and in some cases the administrator can select the "most correct response".
