I came up with this idea: http://codingstyleguide.com

Wouldn't it be nice to have a repository of many Style Guides, where the users can vote on each to decide which one is better - some kind of mixture of Quora, StackExchange, HN... I've been using it since launched and it's definitely helping me out, especially in my side projects with different programming languages. This is just an alternative instead of using a Style Guide generator.
