I have answered your statement about App Engine in another post.

As for Android, it would be a colossal undertaking to implement native support for writing Android apps in Go. How can you say it's "half-hearted" to choose not to do such a massive project? Engineering time is not an infinite resource.

Unfortunately it is Google's policy not to comment on internal infrastructure, otherwise I could comment more on our internal usage of Go. But think logically: why would Google continue to invest the time of some of its best engineers (myself excluded) in something that wasn't of benefit to Google?
