Apple Thoughts: Google Latitude Announces Changes

"One of the hottest trends right now is the rise of location-based services (LBS), which helps friends network and find each other based on their location. Foursquare and Loopt are prime examples of these growing networks."

And now Google is getting involved, but contrary to the commercial, they don't have an app for that. However it does work with Google maps via the web browser. Or to make it easy you can get the Google app and access it there. I'm thinking since most of my friends have a Gmail account, this may be a good option for me. What are your thoughts? Have you given this a try yet? Are you?
