There may be some glitches, but I'm actually grateful for the ability to log into multiple accounts at the same time. I still remember, one year ago, the headaches of logging out / logging in all the time (or using an Incognito tab)... Google only added multiple sign-in last year ( http://googlesystem.blogspot.com/2010/08/google-multiple-sign-in-now-available.html http://googlesystem.blogspot.com/2010/08/google-multiple-sig... ), and, when you use it, there is a big yellow alert message that explains the limitations: "Not all Google products support multiple sign-in. When switching between Google products, the account you’re currently using may change. Google products not listed above will default to the first account that you signed in to using your current web browser session." So, yeah... It's frustrating, but I understand how integrating multiple sign-in in all their apps might take some time.
