no numbers are random. if you could get the same measurements... throw it threw the same algorithm... or realize background radiation trends at the site... if you could calculate the entire world's flow of particles couldn't you determine all of these "random" numbers?
Ok, this is getting philoshopical.. that's one way of thinking, you might be right. However, there are other opinions also. We can argue if quantum events are truely random or not.. it is even possible to claim that actually all possible every quantum based event happens in some universe (multiversum theory). Well, is it random any longer then?
Quite funny to think that according to multiversum theory, every tournament goes on with every possible tables and hand I could imagine. I just happen to see and experience that particular serie of cards. Actually, If you 'believe' in this theory, you might oppose pseudo-randomness..
But truly vs pseudorandomness is something we cannot prove, so let's just leave it ;-) Actually, my opinion is that we really do not know. There are randomness or not, but we really do not know how it is. Pseudo-random is anyway good for me. And actually, player delays makes pseudo random very truely random (I assume every shuffle is made with a new seed which is generated at the shuffle time, which is dependant on player delays on that table *and* the others).
btw, It's very clear that random.org etc are out of question for a poker site. Getting the numbers outside would be way too risky.
