I'm not convinced a clean slate would be more desirable. I appreciated the feature; particularly as I've been rather surprised by who among my contacts has taken to the service thus far. The unfollows have been far fewer in number than the manual follows would have been. I'm also not sure what interest Google would have that would be counter to the user's best interest. What is Google's motivation other than getting as many people as possible to use the service as much as possible? If the auto-populated follow list posed a conversion problem, wouldn't that also be counter to Google's best interest? What's the ulterior motive that is served by auto-follow?
