A lot of it is just fun and silly, but for me it was also an interesting way to develop my taste in something - to hear other people who are real heavy connoisseurs of something discuss it, and learning from them. Of course, you can get this from your friends and the people who are really around you in your life (or, just don't develop your taste at all because you just like what you like), and there's nothing wrong with that, I get why some people find it odd to watch people play video games.
You have to understand as well that Giant Bomb was the first of its kind in a lot of ways, this was an era where video game journalism began to loosen up from the corporate, PR-friendly, very stiff and consumer-focused era it had been in during the dominance of print media, and Giant Bomb was this novel thing where people who had been deeply involved in that era began to find their own voices. If you followed video games at the time online, Giant Bomb was this total breath of fresh air.
