Now that your organization is on Twitter and Facebook, it may be time to think about powering up your social media arsenal with Instagram, a photo sharing mobile social network.

Did we hear a groan? We understand some skepticism when it comes to using just photos to inform, engage and expand community engagement. But with mobile the fastest growing category of personal tech devices, a picture on a phone literally can be worth a 1,000 words and can be used to build new audiences.

For some examples of different uses for Instagram, take a look at some newsrooms experiments with the social network. A week ago, the New York Times launched a primary account, @NYTimes. Other newsrooms large and small have been using Instagram, according to Katie Hawkins-Gaar, who monitors new trends in journalism as Poynter's Digital Innovation Faculty. Poynter has opened an Instragram account. She put together a list of examples that provide some smart approaches:

1. Facilitate crowdsourced projects. The Chicago Tribune is using its Instagram account to showcase work from people throughout the city. With weekly creative themes like "Windows" or "Chicago After Dark", the 168-year-old paper is connecting with its audience in a fresh way.

2. Teasers for long-form reporting. Although most of his reporting occurs weeks before publication, CNN's John Sutter uses his personal Instagram account to document the places he visits and people he meets along the way. Sutter, who reports on social justice issues, later incorporates those photos into his long-form stories, like his 417-mile trek down America's "most endangered" river.

3. Showcase stunning photography. This one's a bit of a no-brainer, but it's a surefire win. Instagram is an ideal platform for showing off beautiful photos and reaching new audiences with a passion for photography. There are plenty of examples of news organizations doing this well, including Time Magazine, National Geographic and MSNBC.

4. Present news in a new format. Instagram is a natural fit for NowThis, a video news network targeted towards people who consume news via mobile devices and social networks. NowThis' feed is full of short videos with attention-grabbing text -- including one surprisingly intelligent take on #thedress.

5. Create a sandbox for experimentation. The Instagram feed for Arkansas' Fayetteville Flyer, an online-only publication, hosts a mix of beautiful photos, questions directed to the audience, and -- yes -- sponsored content. Best of all, though, is the recent photo that helped identify the driver of a Jurassic Park truck.
