BugMeNot.com provides an interesting solution to a lot of gripes about various numbers of websites: How come you have to give away your personal information (name, email, etc.) just to access a site that has free content? (Such as the New York Times).
Well, BugMeNot has the answer. Type in a web address, and you get a dummy name and password you can use (however, this is not for shopping sites, such as Amazon).
