Me too. RethinkDB is my document database of choice these days. In my experience, its proven to be reliable and fast and the development team very responsive and helpful. They also seem quite mindful when it comes to new features and will delay things for years (eg auto-failover, which they now support but it took a while) if rushing it would impact quality.

That's what I want from a database: first and foremost it must be solid and not lose my data. Everything else (including high availability) can come after.
