In light of recent information that is slowly being divulged regarding China's recent attack on google, I am advising people who own Gmail accounts to immediately change their password(s). there is a possibility that the information that was stolen who allow the perpetrators to have cracked Google's password code somehow. I'm not sure of exactly what goes on, but there is enough evidence to suggest that it would be wise for users to change their account passwords. Some of the comments in the article that was posted at the New York Times yesterday is enough evidence for me. Read it yourself:
