A Kindle forum is needed.
1. The Kindle line of tablets and ebook readers is a major player in the gadget arena. Blackberry is pretty much dead in tablets and dying in smartphones and yet it has a forum.
2. Kindle tablets are more popular than any other tablet except for the iPad (in the US).
3. Amazon tablets, while they may use Android as a base, can be considered a separate product altogether because of the Fire's official distancing from Android and the Kindle's focus on being a portal for Amazon.com.
4. It will allow those who are interested in the Kindle line of tablets and ebook readers to have a place to converse, without the assumption that they're interested in Android itself. This is a more welcoming position for newcomers to The Verge and its forums.
