Two decades after creating Digg, a community-focused social message board, Kevin Rose is reviving the site and teaming up with a founder of Reddit.

Digg, the web portal that helped popularize upvoting and downvoting, is bringing in Reddit founder Alexis Ohanian as an adviser.

Reddit co-founder Alexis Ohanian and Digg founder Kevin Rose are backing the deal, with the new Digg to be led by CEO Justin Mezzell.

Before Reddit there was Digg, which popularized up- and down-votes on online posts. Now the founders of both platforms — social media veterans Kevin Rose and Alexis Ohanian — are relaunching the early Reddit rival with a focus on “humanity and connection” they hope will be boosted by the use of artificial intelligence.

Digg was divvied up and sold in 2012, with many of its assets and patents acquired by LinkedIn. Reddit, which launched in 2005 and was co-founded by Ohanian, took a similar approach to let users vote on what they thought was the best and worst content on the site.
