The "youtube herp derp" chrome addon (a joke addon that literally replaces all the youtube comments with a stream of "herp" and "derp", allowing you to right click the comment to revert to normal) has...
Really improved the youtube experience. I often would catch a glimpse of comments, and they were normally awful. Conspiratorial, racist, ludicrously political, wildly insulting, whatever. TERRIBLE.
There are a couple videos with acceptable comments, but you mostly know those going in, and unherping them is trivial.
Anyway, google+ doesn't stop that, and you've always been able to youtube account comment, and whatever. This is actually nice because I've never understood why google felt the need to copy suckerberg and his fucking palace of shit. Now I can actually use Google+- I'd never tolerate my real name returning everything I ever write about anything and to anyone to an employer. The idea that this is ok or reasonable is a laughable mid-2000s idea. We knew it sucked in the 80s, the 90s, and now. Good riddance to bad fucking rubbish.
