Maybe the solution has been there the whole time, or maybe it was just a hot new feature that I stumbled upon, but Google allows multiple accounts to sign in under one browser. Here's how:
- Locate your name in the upper right hand corner of most Google websites.
- Look for "Sign In to Another Account"
- Enter info
There are still inconstant menu choices across Google Services, for instance on blogger.com, there isn't a "Sign In to Another Account" link. Your best bet is gmail.com or google.com.
