A blog is a weblog of events. Wikipedia defines it as “a personal journal published on the World Wide Web”. You can use your blog to notify people of topics that interest you, call attention to subjects you think people should know about, or just keep folks updated on things going on in your life. Blogs have the added bonus of having rich text, multimedia, links to other web pages, other websites, stores, etc. You may have people comment on it and you may not. You may wish to comment on your own blog or not, but you should always read your blog.
