Youtube's front page recommendations have always been a distraction for me. Due to reasons I can only interpret as political, the Chrome store has no extension to disable front page recommendations on Youtube. Thus I wrote a quick and dirty script to remove the recommendations.
Note that since Youtube uses a JS framework that prevents me from disabling the recommendations once and for all, I had to settle for the solution where the recommendations are cleared every half a second. The cost this incurs in the browser should be negligible. Please let me know if you find a better way!
