For me the whole point of browsing is to see something I haven't seen before and to feel like I'm part of what's happening at this very moment in the digital world. When I'm looking for a solid variety of videos I usually just stick to that one hub because they do a great job of filtering out the low-res junk and the interface is clean enough that I can find exactly what I'm in the mood for. It is way better than trying to navigate those messy forums where half the links are dead or lead to something completely different than the title suggested on the link.
