I will argue that 256 coin flips from random.org is the best random number possibility available. And assuming that you push the results through an offline computer using brainwallet offline, you will have a VERY SAFE, VERY RANDOM private key.
LOL. A "VERY SAFE" number which is trivially known to a third party. Is someone at "random.org" paying you to encourage people to have them generate their private keys, or did you come by this cluelessness naturally?
I haven't looked recently but last I checked random.org methods were secret and not peer reviewed. So not only may the results be trivially maliciously logged (by the site operators or anyone whos compromised their system; or the operators of the VPSes they use (rackspace cloud)), they're probably more likely to be accidentally flawed because their methods are not reviewed.
