Great idea, but in order to succeed you need to make the guidelines editable like a wiki, and make the accounts something someone already has.

For example,

- https://github.com/bbatsov/ruby-style-guide

- https://github.com/php-fig/fig-standards

These are editable by anyone and people already on GitHub so it makes it easy.

I don't want to rain on your parade, I think the site is a great idea, just expressing what I think it would need to succeed. I was trying to go to about or sign up and it timed out, I'll be back later to check it out.
