Last week, I talked about a few different Twitter applications that publishers might use. This week, I'm going to show you some innovative digital tools that will enable you to use Twitter for reporting.

I'll mention upfront that I would not recommend quoting directly from a Twitter feed or even using Twitter as your only source on a story. However I think that Twitter can help you find sources, give you context to a certain topic and ultimately aid in your reporting efforts, wherever in the world you may be.

Use Twitter for reporting.

Tweet Scan - This is a great search engine for tweets! Requires login to get full access to all the tools, but it can definitely be used as a reporting tool. Again, you're not quoting directly from folks - just looking for leads and additional context to aid in the reporting process.

TwitterTroll - A workable search engine for Twitter feeds, though not comprehensive. Try running a search for people, information on a store and more.

Twubble - Want to follow more people but not sure where to start? Twubble will make recommendations based on who you currently follow and your geographic location. This is a good way for journos to get started using Twitter, especially if they're not sure who to start following just yet.

Twittervision - Twittervision displays random updates from people around the world. It's a bit like watching an aquarium, and it's addictive. Want to get included? Add TwitterWhere, which will automatically post your tweet location.

TwitterLocal - Filter out tweets from just a certain area. Use it for journalism: Reporters can use this as source material to find out what's happening within a certain range of miles, postal code, state, city, etc.

Twhirl - This is a nice desktop application that allows you to update and read your Twitter account. Use it for journalism: This application really functions more like an instant message client. Still, it can help reporters stay on top of breaking news.
