Some people prefer that their blog cover a wide range of subjects, acting as a general directory with categories of topics that people can browse to find what they want. There are many uses for these types of blogs, such as product review blogs that cover a wide range of products.
Other blogs aim to be more specific and focus on a particular area of interest. These are typically considered to be "niche blogs" and are the type of blogs that I focus on building. These blogs can focus on things such as a particular hobby, sports, etc.
To decide on the type of blog that you wish to focus on you need to determine what the purpose is for the blog. You will want to decide whether you want the blog to be more of a hobby or of you want it to make money. If you want the blog to make money then you will want to choose a topic that can be monetized and also has a good amount of traffic.
Just because a topic has a lot of traffic does not mean that you can make money from it. Currently, the war in Iraq is a high traffic topic, but you may be hard pressed to find a way to monetize the traffic. Alternatively, podcasting, bankruptcy, and the NFL draft are highly dearched for terms and there are ways to make money from all of those subjects.
My blog, TheMarketersMind.com exists to provide help to people who are marketing online and therefor I try to cover all aspects from Affiliate Marketing to Web Hosting and Web Design.
My advice for most people is to start a blog on a subject you know well that you can monetize through affiliate programs or by writing reports that you can sell. Watch out for more on Niche Marketing in the near future.
