est ways to generate traffic are blog commenting, content aggregators, forum commenting, google+, guest blogging, Q&A, reddit, social media, youtube, email, etc.

The best site for traffic is
1. Facebook
2. Twitter
3. Linkedin
4. Instagram
5. Pinterest

There are many sites to get traffic but depending on only one site to get traffic is not a good way, use high PR social media sites with unique content and quality of backlinking will help to get traffic for your site.

Popular forum and social bookmarking sites can drive huge traffic.
You can also use social networking sites.

Try Quora and Pinterest. They both are working fine for me. However, I prefer and working smart to drive organic traffic :)
