To be honest, Digg is actually very good for redirecting traffic to your website. After doing a lot of research I have some facts I would like to share with u. A single comment on a trending post keeping in mind that the link provided in the comment is relevant and interesting for the user who clicks on it, you can get upto 400 views in a single day. Not Kiddin..! But to everyone's surprise a newer site called Reddit has become even more popular. The traffic stats are enough to present that. Find the job that truly suits you !
