I don't think there's as bold a line between Personality and Content as you might think.
I'm a big fan of Giant Bomb, and yes it is largely because of entertainment reasons, which is where the personality mostly goes.
But when they talk about games, because I'm spending time watching and listening to these guys for hours and hours a week, I get to know their personalities, and how they align with mine. This is especially useful when it comes to reviews. Everyone is going to approach a game differently, and because I'm so familiar with their personalities, I can use that to get an even better idea of a game than just a stock review by someone I've never heard of.
It also doesn't stop them, especially Patrick, from being able to put on the investigative reporting hat when it's needed. He's still one of the best in the business when it comes to straight up Scoops, but the fact is that a 24 hour news site for games ends up a barren hellscape. If you want sustainable traffic that doesn't rely on big current events or games or hot scoops then you need something more. Whether that be editorials, dev interviews, vaguely game related bullshit, or quality video content.
Yeah, the Games Media is probably moving steadily towards more personality driven content, but that doesn't mean the old kind will disappear entirely, nor is its quality necessarily compromised.
