Support for tooling, ease of hiring both programmers who are familiar with querying and DBAs is much better on relational. The pain caused by relational being a 'bad fit' needs to be pretty high to consider NoSQL in my opinion. Except for hobby projects (I did some CouchDB stuff in my spare time for the thrill, but MySQL would have been adequate.) True, noone is born with SQL knowledge (learning to breath is the first priority). However stick your ad up for an experienced Cassandra DBA and then an experienced Oracle DBA and see how you do.
