WOW! I had exactly this idea at a Hackaton festival called Codebits in Portugal in November last year and presented it[1] to the audience but didn't receive that much excitement from them about my implementation done in 12 hours using JS and Rails3.<p>Now I see I should have stick to it. Deep inside me I knew if the service would be useful to me, it would be to some other folks, but I was a bit disappointed and didn't correct the bugs that the project had.<p>Here is the website if you guys want to check:<p>[1] <a href="http://youtubemyplaylist.heroku.com/" rel="nofollow">http://youtubemyplaylist.heroku.com/</a><p>It is buggy, sometimes doesn't change to the next video and it lacks the controls and the display of the playlist as this site does and it is a lot slower. It also lacks the upload of a text file. But I had other ideas in mind, the mode implemented was supposed to be the "feeling lucky" mode, where you just typed each video one per line and hoped it would match to the video you wanted, but you'd also have a way to create playlist more carefully by passing the exact urls of the videos you wanted, like this site does.<p>How do you overcome this feeling when you know you should have sticked to your guts?<p>Anyway, good work guys! This is exactly what I wanted.
