Jakers has to have more information than we do. To me, he's the same smug and vapid poster that he's always been.
He's interesting because the arrogance seems to be tied to his intelligence but he doesn't seem interested in having an intelligent conversation or sharing intelligent thoughts.
My guess is that he found a posting style that makes him feel superior without ever having to actually back it up. He's probably not actually like this in real life, and that's why Jakers tolerates him.
