Comments: You should probably learn more about Riak. The "From MongoDB to Riak" is light on details but isn't really hand-waving. The author is saying that having a masterless database results in less fretting. http://wiki.basho.com/Riak-Compared-to-MongoDB.html
Also, why two rage faces? Can't you get your point across without resorting to silly memes?
