Looks very interesting. Have some feedback though:
* I couldn't identify what license the code snippets are shared under. Could you add an option of license selection when a person posts? (Default could be GPL)
* The links for 'Privacy Policy - Cookies - Contact' are only available on the Home page, not when I am browsing the snippets.
How about Title list and on mouse over OR on click - POPOVER the code as well as option to open in new page.
