This seems like a complaint looking for a problem. NoSQL is a very broad term -- are you talking about Cassandra, MongoDB, CouchDB, Redis, Memcached, Tokyo Cab

This seems like a complaint looking for a problem. NoSQL is a very broad term -- are you talking about Cassandra, MongoDB, CouchDB, Redis, Memcached, Tokyo Cabinet, neo4j, etc.? Scalability is one piece of the puzzle; picking the best tool for the job is a much bigger piece. Work with what you are comfortable with, but realize that an RDBMS may not be the best way to deal with a graph. Logging is probably not best done through an RDBMS. We have tools that we can use to solve problems in a more efficient way, so we should use them. RDBMS are not a panacea and neither are NoSQL database solutions. Use the right tool for the job.
