Social Printshop has launched a new website featuring several new products, including a print-your-followers Twitter poster. The bootstrapping start-up (aka Social Print Studio and Printing Facebook), founded by an MFA student in San Diego named Benjamin Lotan, has been growing over the last few months, swelling to a 10-person team since we covered its first product, a 20” x 40” high-resolution print of your Facebook friends’ faces. Social Printshop has even attracted the attention of a few potential investors, including a professor at the Columbia Journalism School and a soft-core pornographer.

In the last few months, Lotan tells Fast Company, he has been trying to define a brand. “We’re trying to claim a space a little bit,” he says over the phone, either hesitantly or groggily or both. “We’re in the space of photos, printing, and social. I’m not terribly proud of these products, I just felt it necessary to push them out. They’re really simple products.”

He’s working on two iPhone apps that he declines to elaborate on publicly at this point, and he is developing a site, SuperEgo.me (a URL he has owned for a while–“it just needed to be bought”), that he intends to be a powerful photo-sifting engine along the lines of Pixable’s photo feed, which assembles and sorts all the thousands or tens of thousands of photos you have access to Facebook. All he has for the time being, though, is a splash page, and he says “I’m not sure I’m prepared to talk about” exactly how SuperEgo.me will outdo Pixable.

But it’s not all vaporware at this point. Lotan and his team have been churning out real products, too–on top of the old standby, the Facebook friend poster, and the new Twitter poster, they’ll print out nice vinyl Tumblr posters, miniature photobooks, and small stickers with images from Facebook, Twitter, or Tumblr. They’ve teamed with Mashable to wallpaper its New York office with images of fans of its Facebook page. Why do people want to order a mosaic of faces staring at them? “The language people like to use is, they want to honor fans, put them on a wall, have them present,” Lotan says.

Recently, when a PR firm met with Bacardi, it paid Lotan to decorate a space with Bacardi’s Facebook fans, “just to help the client be able to visualize who they’re interacting with,” he says. If you think about it, printing out a Facebook fan page is something quite similar to what pizza parlors have been doing for decades when they tack up Polaroids of their visitors. Lotan says, in fact, that he’d like to work with restaurants, but hasn’t yet.

Nonetheless, Lotan’s progress has been considerable enough that he’s attracted attention from at least two potential investors. Matt Paolasso, a musician/photographer/actor/soft-core pornographer/”man of mystery, hysteria, and lore” (according to the gentleman’s site), has been talking to Lotan, who also hopes Paolasso might help make content for the site. “I’m not saying we’re gonna make porn,” Lotan adds, just standard PG-rated promotional videos. A Columbia Journalism School professor intererested in social media also reached out to Lotan about possible investment.
