I'm actually not that worried about corruption as that is something that 
can be fixed once discovered. What creeps me out about btrfs at the moment 
is this:

The fact that the FS needs manual rebalance operations and that these can 
"take a while" (even tough this can be done online) doesn't exactly make 
btrfs the ideal candidate for an end-user desktop system that should pretty 
much be able to look after itself.
I'm actually quite interested in btrfs especially for servers because of 
it's features but this problem really worries me.
