You can use Google Alerts to stay updated about anything you're interested in, whether it's a specific keyword, phrase, or topic. You can create an alert for just about anything you can think of, and customise it to suit your needs. For example, you could create an alert for:
-A specific keyword or phrase
-A specific news story
-A specific blog post
-A specific forum discussion
-A specific website
You can also specify how often you want to receive alerts, and where you want them delivered (e.g. to your email address or RSS feed).
