tube.poal.co was based on invidio.us, and the problem was about Joogle blacklisting poal's server IP with a captcha so it was impossible to use it anymore. The devs then started crippling the code like hooktube did by removing features. That's when we decided to move on something else. Nodetube was a perfect candidate and its amazing dev is also a poalr (@anthony_newtube) :)
