As my firend says, not all engines use the attribute. Also, while Google not double listing content in this way, other engines may do so - and Google will not take kindly to you have duplicate content indexed elsewhere (at least, this is what I believe). I also have no desire to allow a printable thread, if they wish to print the thread so much they can print the normal page (or now, use this).
Also, I intend to allow only members access to this - so no duplicate content issues there.
