To a lot of people, snobbery has negative connotations, but there are some places on the web that could use a bit more of it. The best example? YouTube comments. A lot of the commentary on YouTube videos lacks substance, proper grammar, and semblance of constructive criticism. That's where YouTube Comment Snob comes in.

YouTube Comment Snob is a Firefox extension that gets rid of a good majority of the spam and drivel by applying some simple grammatical rules. You can customize it to filter out comments by using your favorite combination of the following: too many spelling mistakes (using Firefox's spellchecker), too much capitalization, no capitalization, swearing, profanity or excessive punctuation (!!!???!). The only problem with YouTube Comment Snob is that it hasn't yet been applied to the whole Internet.
