logging to STDER seems more prudent - just in case someone tries to pipe some output into another command. also, it's never buffered.

In what context do you expect someone to pipe from ./script/rails console?

so, i have this

a side effect of always logging is that sometimes you want to turn it off (note my ENV test). in the case that you log in STDERR you can simply do:

rails c 2>/dev/null

even better you can do

logging on STDOUT is simply being a poor unix citizen, but letting the user decide where the logging will go you can facilitate alot of neat unix tricks.

also, serious issues can arise with buffering and bad terminal settings. STDERR is not buffered and just this fact prevents a lot of headaches.

put another way - what good reason is there for ever mixing output with logging?

I don't disagree that STDERR would probably be more appropriate, but buffering is irrelevant in the context of an interactive console.
