If you like watching Youtube videos, but you'd rather see them without all the additional screen clutter such as suggestions, comments, lists of other videos by the same contributor and so on, then you'll be interested in this Hot Find. ViewPure is a web site that lets you watch your chosen Youtube video on a blank screen (you can choose black or white), with no other distractions. Which saves your internet bandwidth, and thus makes everything cleaner and faster. To use it, just head to http://www.viewpure.com and paste the URL of the Youtube video you want to watch into the box. Then hit the button and watch in peace, on your de-cluttered screen.
A couple of alternatives are streaming Youtube vids to a standalone media player such as VLC or Pot Player, or using the Pop Video add-on for Firefox which as the name suggests pops the video out into a separate dedicated window. Quietube is similar.
