Well looks like the Google Mobile blog has closed, but in its place has arisen something every reader here is much more interested in anyway. The Official Android Blog, a blog specifically about Android which contains news and notes from the Android team. Google has imported all the Android based posts from the Google Mobile Blog so that nothing is lost and will continue forward with this from now on.
The sidebar contains links to all the other places you can get your official Android news such as the RSS Feed, link to @Android on Twitter and of course a link so you can add them on Google+.
