You can do lot of interesting stuff with Google Talk like get alert notifications, save bookmarks to delicious, manage web calendars, set reminders, write blogs, and so much more.
Such features can be easily integrated into Google Talk through ‘bots’ which, in simple English, are like virtual friends who are online 24×7 and will always respond with a smile to your questions or requests.
