I think most streamers are full of shit and usually it looks like they just hop onto whatever game is a big hit at the moment to get more youtube views. With that said, if it's something you want to do, do everyone a favor and buy a decent fucking microphone and learn how to use it. Holy shit. 9/10 times I see a streaming video to take a peek at a game I might be interested in and I can't make it more than 20 seconds through because my ears and eyes start to bleed. It also helps to have a voice that isn't absolutely horrendous, which seems to be a theme with these people. Because their parents told them they have a "unique" voice, they got it in their heads that other people will enjoy hearing it. Now excuse me, I gotta clean up this vomit off my keyboard.
