Facebook runs many thousands of btrfs filesystems every day, and it seems to works fine for them. They have helped to iron out a lot of bugs (and developed several features for it) I personally have been using it for maybe 7 years and it works just fine, and snapshots are awesome. To me, btrfs is being more stable than Ext3/4 back when I used them.
