I generally go to YouTube for specific things, so I don't have much use for the trending page. I just looked at it. There's a lot of crap on it that I wouldn't watch anyway.

All commercial web sites make money from advertising and revenues are tied to visits or views. Therefore, almost everything that a site like YouTube does is designed to increase traffic on their page. This particular feature is not necessarily a bad thing as it may expose viewers to a broader range of videos.
