I want to start up my gaming Youtube channel but I want to know whether I should do live commentaries or post game commentaries mostly. I plan on playing TF2 and I have problems with with both ways. With the live I feel like I may be uninteresting or ramble on about dumb things, and with the post game I wouldn't really know what to talk about because I'm not one of those MLG players who knows everything about maps and weapons and such, feedback is appreciated!

Thanks for the answers, I'm glad that everyone is so ******* lazy that they simply can't pick one or the other. :)
