I have just recently figured out how to keep track of all my favorite blogs using Google Reader. You just set up an account (which you might already have if you blog with Blogger). Then you can search and add feeds to your main page. I had been doing this with My Yahoo!, but dropped them last week because my page wouldn't update to show new posts (maybe it was operator error, but I don't have time to figure it out).
So then I discovered something even cooler. Many job search sites will let you save your search criteria as an RSS feed. So, you just go to the site (for example, Monster.com), plug in your criteria (industry, location, and keywords, such as "editor"), and click the Search button. After the results come up, there is usually an RSS button you can click that sends these exact results to your Google Reader page--and updates them automatically as new jobs are posted. What could be easier?
In addition to Monster, I have found RSS buttons on Indeed and Simply Hired, two very cool "aggregators" that pull jobs from everywhere on the Web, including company websites. I was unable to find this feature on CareerBuilder, though.
