The years went on and she got a Gmail account, but she would log in to Yahoo every year or so to read through her old journals to help process what was going on in her life.
Only one year she tried to log in and her account was gone. Yahoo, she learned, simply deletes your email if you don't log in for a year. And she had gone 14 months.
Personally, I think deleting data like this--especially when the storage requirements are so tiny--is unforgivable. I can think of many, many reasons why someone would put something important on Google Groups and then not log in for six months. There are people away for Peace Corps right now. There are people deployed in Afghanistan. There are people hiking the Appalachian Trail (well maybe it's a little late for that).
Many thousands of people will feel completely violated if Google does this. Google can count on that. For those people, Google will have simply destroyed their most precious data without warning.
I used to think that one of the selling points of Google Apps was that I could leave my data there and trust them to protect it. No more worrying about crashed hard drives. But it's become clear that's not the case.
