Google is sure having a tough time lately with it's recent product releases.
First they had to deal with the backlash against the Wave product as the overwhelming consensus from the public was confusion. Wave was supposed to be the new generation of online communication taking aspects from email, instant messaging and social media but in the end it seems Google missed the mark from a usability perspective.
It looks like Google is at least smart enough to recognize their mistake and is already taking steps to correct the mistakes made with Buzz. They announced they will stop automatically linking you to the folks in your address book. Also, they will stop forcing Buzz in the Gmail menu but rather it will be an option users can turn on and off.
