Thanks, that's great! We should write a general comment removal framework and launch an online script database to remove all the shit around the Internet by clicking a button! Of course remove GitHub comments is not necessary.

@biergaizi That actually might be a good idea. Check out this talk if you haven't already. Would love to just skip the comments sometimes and reclaim my scrollbar.
