Writely sent out emails to all registered users the other day which said that they were switching over to Google Authentication. I figured that meant that they were going to make a complete switch over to Google including changing the logo, branding and layout. However, the login box is the only thing that has changed.
I was a little disappointed that they didn’t make a complete switch over to Google but I guess they are probably doing it little by little to make sure that something doesn’t go wrong. They did do a nice job of making the switch to Google Authentication because I still have all of my files available that I had available on Writely. That would really suck if someone lost all of their files.

Yes, but might that be because you were already signing in with your gmail account? I can’t see how someone would migrate their files from a login like some_schmuck@yahoo.com over to cool_guy@gmail.com without first having to link the two accounts. Any ideas?
Yep, this should be the case. Otherwise they cannot know how to relate different emails… unless they really spy our online-life.
They won’t be transferring files like that, but a writely account such as cool_guy@gmail.com will not have the files deleted instead you will be able to login as normal.
