Blog: Blog seem to be the next big hype out there, yet there is still some confusion as to what exactly blogs are. Blog is short for web log, which is essentially an on-line journal or newsletter that is frequently updated and intended for the general public. A Blog can have either one author, coined blogger, or several.
Forums: Forums are different from blogs because they are authored by numerous individuals, and are more like open discussions then individual diary entries. Forums provide a place for those with similar interests to share their thoughts, questions, etc. Users generally log in to read and post to current subjects being discussed. Forums also come with special features such as personal profiles, calendars, and email notification systems.
