One of the big commentators in the golden age of SC commentaries (Cholera, Klazart, Moletrap, Diggity, Rise) (Nuke is newer I think).
Just uploaded his first video in a long time, casting OSL semifinals, has the entire Jangbi/Zero semifinals up already.
Was a huge fan, can't wait to see if he gets back into commentating
Edit: I can't directly link his videos on TL without E-Sports TV getting mad, so here's a link instead to his youtube page:
He says in his videos that the reason he dissapeared was that a lot of stuff came up; he finished "schooling" (probably college), got a new job, and is getting more schooling (probably md/phd), so he was in a transition phase and didn't have time to commentate.
