From what Shibby told me, he said that he couldn't adapt to the newer generation members. You, me, Al-pucino, Latiosmaster and etc, also the newest of the new (a.k.a. newbies and spammers). He didn't have too much to stick around for, so he left... I feel for him, I really do.
Just to honour him, let's let this pass quietly and humbly. Like Shibby said, Neo would like it better if he went away quiet and dignified. Please, no spectacles out of this.
