I think it would be helpful if there were more categories. Separate the Jar Talk, TNT, Load Our Last Save, Random PC Game into their own categories. Right now it's a pain to navigate the video section when they are all dumped together. It's also hard to find a specific video because the description doesn't, er, describe enough about the video. I tried to find an old TNT where they played the Ticket to Ride board game but there was no way to search for it. I had to just use Google. Google Search shouldn't be more helpful in finding things on a site than its native search feature.
Finally, it would be nice if the site linked to the archived videos on Justin.tv (and labelled correctly) since many newer users won't have any idea they exist. There are hours and hours of pure gold archived there that aren't on the main Giantbomb website.
