Chris Poole — better known as “Moot,” the founder of the Internet forum 4chan— has started a new project. (I’d advise avoiding 4chan’s /b/ board while at work.) Canvas applies the same culture of goofing off and just hanging out online as  its sister site to images. Poole launched the new venture at South by Southwest and it’s sure to be a meme-generator in its ownright.

In Canvas, users post, alter and repost images, riffing off each others’ ideas and letting the images take on lives of their own.

Unlike 4chan, however, Canvas requires registration through Facebook Connect. According to PC Mag, Poole said that many fans of his first site have panned the idea of using Facebook to log into the site, but he decided to use the service as a first line of defense.

“Facebook really just a first pass at weeding out your more casual trolls…who might muck the site,” he said. PC Mag reports this may have to do with the fact that the site is backed by investors such as Andreessen  Horowitz, SV Angel, Lerer Ventures, Founder Collective, Joshua  Schachter, Chris Dixon, and Caterina Fake.

Despite its nod toward validating identities for registration, Canvas allows anonymous posting, which Poole defends as a way to show a more authentic part of human nature.

In his keynote speech at SXSW, he took issue with Facebook CEO and co-founder Mark Zuckerberg’s stance that users want a single online identity. Even when registering with Canvas through Facebook, only a user’s friends already using Canvas will see his or her photo and name, and only on the invite page.
