Why?
- Staying up-to-date on the news in your industry/area of work
- Knowing what people are talking about
- Finding reference resources for later use
They, of course, reference their earlier post on the subject, the one I linked to above, and then gave some concrete examples of finding blogs for HR professionals, Physical Therapists and Fire Inspectors. You can take these same techniques and use them to find blogs that will help you keep up-to-date with what others in your job are doing, talking about and thinking about. You can also use alert services such as alerts.com to pull information about a particular keyword into your feed reader. Another tool that you can use is a custom search engine that does constant searches throughout the web for information you want and dumps the results into an RSS feed for your feed reader.
Using these tools, you should be able to find blogs that will pay off handsomely in your ability to stay on top of what is going on in your particular job. Just going through and doing an alert or custom search for keywords will really help you identify what blogs are discussing topics you care about.
