Suggestion: It would be great to have a page on your website that explains why RethinkDB is better than the other prevailing options. Right now I don't know why I'd want to invest time setting up yet another database.
Can you talk a bit about how RethinkDB compares?
As an example, I like how Basho provides some comparisons[1] of Riak vs other popular options.
