If you look for post-event discussion, opinions about how playstyles changed (and will/should) in different matchups and upcoming patches, then you really should watch/listen some State of the Game podcast episodes:
No idea what the hell State of the Game is? It is a podcast based around the happenings of the SC2 world(*). The Pillars of State of the Game [fancy way of saying the hosts]:
JP 'itmeJP' McDaniel, Sean 'Day' Plott, Dan 'Artosis' Stemkoski, Tyler 'Liquid`Tyler' Wasieleski and Geoff 'EGiNcontroL' Robinson
Most informative site I know for this is the Official State of the Game Podcast Thread on TeamLiquid.
Recently they tend to invite some other persons to the talk, these are players (Destiny, NaNiWa, HuK, White-Ra,...) or other important community guys e.g. the manager of Complexity Gaming, some TL-staffies or people who make StarCraft-related documentaries.
I usually find time to listen to it every week when walking or sitting in the bus. And most of the time its hilarious to listen to these guys!
