Richard Byrne writes: “I have long said (half jokingly) that YouTube comments are a lot like the graffiti you find on the walls of dive bar bathrooms. In other words, nothing good is found in them. There are some exceptions to that rule, but they are few and far between. It seems that Google agrees with me because they recently launched Tune, a Chrome extension designed to hide toxic comments on YouTube, Twitter, Facebook, Reddit, and Disqus. Once you have the extension installed, you can choose which networks you want to apply Tune to. Tune will then attempt to identify toxic comments and filter them from your view.”
