I run btrfs on my main arch installation. Have for ~6 months. If you get the fsck.btrfs tool (it is upstream) you eliminiate the only real showstopper with btrfs on Linux.
You get the online compression (meaning you use less space and read and write faster on mechanical storage because you have less to read / write at a time), you get the snapshots, you get subvolumes, checksums, etc.
I follow the btrfs development because I'd love to have at least the features of ZFS on Linux. However I would not dare (yet) to use it as a replacement for my current home fileserver (which owns ALL my data).
