What do you like to watch and where? Youtube? JustinTV?

PsyStarCraft on Youtube. He focuses a lot on Zerg, so it's good to take in in order to play/counter Zerg.

Definitely day9, he is the most entertaining, enthusiastic and helpful. I sometimes watch Psy's videos too, but I don't play Zerg so...

Day[9], as everyone's saying. Psy isn't just informative, he's also very entertaining. If you're looking to learn from the videos primarily, Day[9] is probably the one that will give you most most information. Psy, on the other hand, will show you a lot of Zerg-centric play (for learning how to play or play against Zerg).
 
SCAudios has some good stuff. You can basically YouTube search any of the big players for some good commentaries: TheLittleOne, WhiteRa, Idra, Huck, etc. 

SC2Casts.com has pretty much every important match on it. Not really in to Starcaft but I kind of enjoy watching them for some reason.

I tend to watch more in Korean now, kinda sad but I end up watching them live...and just gotten used to it.  x.x 
 
You get the jist of what's going on, but the sheer dedication to how focused they are is just amazing.

I compusively consumed every bit of Starcraft 1 media Day[9] put out.  Now I'm watching his SC2 stuff even though I've yet to play the game.  His 100 episode special tells the story of how he was a pro-gamer - definitely watch that one if that sounds interesting.

I really enjoy JoshSuth (aka AskJoshy on youtube).    He is a commentator for iCCup.tv and does a lot of iCCup's tournament casts, which is pretty awesome and his commentaries on youtube are pretty fun to watch.

Day9 /endthread

PsyStarcraft is about the only one I really watch anymore, he's the most entertaining and informative for me as a player.  Moreso than Day9 even. 
 
But take that with a grain of salt, as I am also a Zerg player.  Non-zerg players probably won't find it as useful since he tends to focus specifically on the zerg player in all his casts.

I'm  a fan of these guys as well:

and of course, Day[9] 

Another vote for Day9, he's a must if you want to learn and improve your game. I like what I've seen of Psystarcraft too.

If you are looking for a podcast, there is a pretty interesting one run by JP McDaniel of MLG.  It's called State of the Game and features JP, iNcontrol, Day9, and Liquid`Tyler (aka NonY) + a random 5th person every week.  They talk about players and tournaments (they spoil the SHIT out of the GSL this week, so Spoiler Alert there!) and patches and all sorts of goings on.
 
I only know the thread on TL.net, but they say it is available on the iTunes and other what have you's. 

watch psystarcraft, he's one of the top zerg players and he does LIVE casts of his own games sometimes....and he's hilarious

Day9 is great

Day9 is the one i found most informative, and with his new fundaymonday's and noobtuesday it's going to be more interesting to see different tactics from other then diamond ladders.
