Ever wonder what people are saying about a certain subject on the Internet? Or maybe you just wonder what they're saying about you? If you go to Google Alerts, you can set it up so that you receive email alerts about any topic -- a news story, a sports team, a favorite author, a distant cousin.
For example, if I wanted to know what people are saying online about my homeschool book, I would set up a query for "Catholic Homeschool Companion." I could then have Google contact me immediately, once a day, or once a week. I could also have Google notify me of everything on the web, or I could set it up to only notify me of blog posts or news stories, etc.
This is a neat little tool.
