Given that some 35 hours of video are uploaded to YouTube each minute, sifting through to find exactly what you're looking for can be a challenge. Enter Devour, a site dedicated to hand-curating (humans, not algorithms) hilarious videos every day. According to the site, they provide, "Fewer cute kittens, fewer skateboarding nutshots, fewer tween heart throbs, and lots more awesome."
And it's true. A quick visit to the site produces no fewer than 10 videos not only worth watching, but also worthy of sharing with friends. In addition to the home screen, videos are organized into categories like Animals, Commercials, and Short Film. You can even customize the look of the site (its Wallpaper background is my favorite) with different background and layout options.
