think of this:
All the content you want updated constantly in one place.
You put in the search parameters then sit back and revel in your own laziness.
Set up a GMail account
Go to http://www.google.com/alerts
Lets say you blog about upcoming movies. Google Alerts lets you base your alerts on the parameters you specify...like The Hobbit
It can then add the alerts to either your feed (via Google Reader (another tool you NEED to use) or in your email. I HIGHLY suggest using Google Reader...just Google it for more info. Below is a screen shot of my Reader, which includes blogs I'm following along with the alerts I've set. All in one place so you can be up to date on the latest news on whatever topic you want!
It's insanely easy to set up, however be cautioned, it is very easy to get wrapped up in whatever you are following and forget that you need to WRITE.
As always, find interviews, writing samples, videos, contests and more on my website.
