Ionut Alex Chitu on how Google handles feature addition and removal:

For Google, features aren’t a “one-way street” and you never know when a functionality you start to rely on is removed for unknown reasons. That’s why I think Google should label experimental features more prominently and it should do a better job at communicating the reasons why a service is dropped.

While I’m sure services like GMail (which is still in Beta) will not be removed, it is a little frightening at how much of our information Google holds, and is completely at the mercy of their corporate whim.
