DiggitySC: The premier Starcraft commentator. Posts much, much less these days, but this guy is absolutely the best.
Violetak: This account is used for dual commentaries. Almost dead, but when something goes up here, it is worth seeing.
Moletrapp: The most annoying and unprofessional commentator out there, but at least he posts frequently and has great knowledge of the game.
NuketheStars: A very professional commentator, and has high production value. Posts frequently.
TheThinkingGamer: A brand new account, has been posting tutorial videos. Some are amazing, some are poor.
HuskyStarcraft: I haven't watched much here, but seems to post prolific SCII stuff.
