I think we could use a blog too.
Edit: I've also seen this: http://blogoverflow.com/ but I'm not sure if this is authorized or not.
Pretty sure that it's official. See this thread on Android chat last week http://chat.stackexchange.com/transcript/25?m=757179#757179 that links to the Community Blogs chat room http://chat.stackexchange.com/rooms/115/stack-exchange-community-blogs
We now have a set a guidelines for Stack Exchange Community blogs, so make sure you check out How are blogs created? for details on getting one for this community.
