Aside from the percieved invasion of privacy that Google may be perpetrating in its information gathering, I think they are amazing, from Google Docs to Gmail to iGoogle.  I may be behind the curve a bit, but I just found a cool way to keep track of any topic on the internet, where ever it may arise. Google has a service called "Google Alerts"

It is a web search tool that you can iput certain search terms, and whenever something is updated on the internet with a specific phrase, or even a general topic, you are sent an email with a link to the web page.  I have been using it to track the progress of the "Utah Home Run Grant" and I have an alert set up for my name, so anytime anyone posts something about me, or my namesakes, I am alerted.
