I agree. That's what sucks about our dependency on Google too. Most Internet businesses are dependent on them and they can decide to remove you from the index as quickly as Twitter disabled the StatTweet accounts. Twitter effectively removed me from their index.
There is a difference between depending on Google and depending on Twitter. Google is a multi faceted business, they have a good revenue model, have money, and are a proven company.

Don't trust the cloud. Appreciate its gifts but don't expect it will always be so.
