One of the draws to Mongo for me is that there are already existing cloud-managed service providers (MongoLab, MongoHQ) that hook in to Heroku, which is my choice for deployment. I haven't found any real cloud-managed services for Riak except Joyent's smart machines (which are expensive for my small project budget). The other reason was Mongoose, a great ODM for Node.JS that makes my life a lot easier.
Of course if anyone has managed to hook into a Riak provider on Heroku I'd love to be proved wrong.
And yes, I could always spin up an EC2 instance and manage a Riak cluster myself, but my time is constrained and I'd rather focus on getting my app out the door than sysadmin tasks.
