I can't agree. MongoDB 2.8 with WiredTiger is a performant NoSQL solution. The way you solve things in document dbs like MongoDB is the key - not the fact that you get competitve performance in RDBMS as well. I like Postgres and the possibility to easily use JSON data. But I still prefer to build applications the NoSQL way...
