MongoDB Zealots I hear you say? Wherefore art these zealots? I watch social media for MongoDB on a regular basis and I can't say I have come across much zealotry in the last 8 years :-)

Most of our customers are reasonable rational people who use MongoDB alongside a collection of other database technologies.

Personally as someone who has worked in pre-sales and more recently developer relations, at MongoDB I find our customers and users are suspicious of zealots.
