Megan Garber October 26, 2011One of the most common complaints about newspapers’ adaptation to the digital world — or, depending on your perspective, their lack thereof — is their failure to create their own versions of Craigslist. Papers ceded the market of micro-marketing, the complaint goes…when, with a bit of foresight, they might have built platforms that might have preserved, at least to an extent, their all-important classified revenue streams. So goes the argument. But it doesn’t follow that, in 2011, Craigslist has completely cornered the market on classified advertising — or, for that matter, on community messaging overall. Today, a major paper is getting into the community messaging game: The Guardian is launching n0tice, a social news platform that draws a little from Craigslist, a little from Foursquare, a little from Ning.
