There have been numerous attempts at so-called “citizen journalism” news models.. The most successful model has been, well, blogs in general. Getting users to contribute journalism to some unified site has been more of a mixed bag. A recent launch in this space: AllVoices, previously known as Masala. Last summer the SF-based company raised $4.5 million led by VantagePoint Venture Partners, while still in stealth. The site, which recently came out of beta, culls news from a variety of feeds, a la Google (NSDQ: GOOG) News, while also allowing users to contribute news directly. Mobile users can report news by sending text, images or videos via SMS or MMS to the site or to the site’s specific channels. In addition to news organized by category, content is also featured on a world map. The challenge, as always: building up a critical mass and filtering for quality. Vancouver-based NowPublic is probably the most well known in the space.
