Best+Uses+of+the+Internet

Other than finding materials for classes, how do you most often use the Internet in your daily life? Check out some of my favorite sites in Vista's Best of the Internet folder. What Website(s) would you recommend to others for a particular purpose? Please provide a link to each site (so others can check it out) and describe why you feel it is so dynamic. Finally, analyze what types of tasks the Web is best and worst suited for. For example, you might look for a new car online but might not want to actually //purchase// it online (without a test drive). I guess the same might be said for online dating... :) (D. Tiene).
