Agreed, Btrfs has been out for quite a while. I think it is only now beginning to become more widely accepted or noticed by the broader community, which is both a blessing and curse.

That said, I'm going to continue to opt for Ext4 or XFS for the time being, even on distros where Btrfs is the default. Probably in a few years I'll get around to upgrading to Btrfs.

I use XFS too, but some large companies such as Facebook have adopted Btrfs on their servers.
