That's news to me, I'm seeing exactly the opposite: NoSQL, and especially MongoDB, seems to be the rage in my environment. I'm not as up to date as the average inhabitant of Hacker News, so I guess I'm just out of touch.
More likely than you being out of touch is that you're in a different environment than I am.
Personally I don't believe people have to pick sides. It's not a war, more options are a good thing for people who have to pick databases.
