Digg has been gaining a few more visitors lately, thanks to its new feature, Diggbar. The site is estimated to have 8.8 million unique visitors in the US,  a whopping 31 percent increase from that of the last three months.

Digg has been recently making web design tweaks, all of which contribute to the site’s growing popularity. One thing that’s become quite notable is the addition of Diggbar. Following its launch, Digg saw a significant lift in the number of visits, attributed to the short links people have been passing around.

Digg is a user driven social content website. After a content is submitted, other users review and “Digg” it if it suits their taste. If a story gets enough Diggs, then it goes up to the front page where visitors could see.

Kevin Rose, Digg’s founder, saw a great potential in publishing stories before anyone else did. Digg rose to fame when Paris Hilton’s phone was hacked, and images and contact numbers were posted in the site. Since then, Digg made huge traffic from all over the world, attracting acquisition offers from industry moguls. The site is currently among the 100 most trafficked websites. It came across more than a few hurdles over the past few years, but it still remains one of today’s social news leaders.
