Hi, this is an add on that's worthwile. I like the vodpod site, it's a nice way to collect any video you come across on the net. I save those i like to watch again or to send to a friend if it's related to something we were talking about.
The add on makes it ever so easy, because it works for any site, so it's not only youtube. All you do is click the button and save the video, you can add/remove comments and tags as you wish. No other crap around it, spam free, just basic click and save.
Thumbs up for this one,i have never had any problem whatsoever with it. The vodpod site even shows when one of the vids has been taken offline.
