There are many different genres of blog. Here are some of the principal ones:

1. Filterblog-- Record interesting links the author finds surfing the web and sometimes annotates them. Example: Robot Wisdom

2. Personal blogs/online diaries-- Articulates an individual's perspective on daily life, relationships, culture, society, politics and everything. Example: Dooce, Ye Olde London Blog

3. Topic blogs-- Solo or multi-authored blogs devoted to a particular subject or hobby (e.g. politics, painting, copyright law, web design, etc.): Example: Crooked Timber

4. V-blogs-- Can fit into any of the above genres but makes use of embedded video instead of text as a means of expression. Example: Steve Garfield's Video Blog
