Many years back before this NoSQL madness took off, I was building my own "NoSQL" database. It was fast, refreshing and it seemed like common sense. Then as I was adding more and more features, I realized my neat "NoSQL" (I didn't call it this though) database is turning into relational one. I've come full circle back to relational stores. Only then I fully understood why relational aspect is mathematically superior to any other paradigm out there and why it's only SQL that really sucks. Perhaps this will happen again to mainstream NoSQL movement. It certainly wouldn't surprise me. So instead of making surveys why enterprises don't jump on NoSQL bandwagon, I would be more interested to know how many of NoSQL adopters ever heard of Codd's theorem or how many of them can differentiate between SQL and relational model. Relational model is a good thing, throwing it out and start from scratch feels like throwing out the baby with the bathwater. That's how I feel about NoSQL movement.
