Quora, the question-and-answer website publicly launched in summer 2010, has released its first official iPhone app today, free on the App Store. For those not familiar with Quora, it’s a community-driven resource for answers on a variety of topics including technology, science, sports, media, health, and more. Quora aggregates topics and questions, allowing users to collaborate on them and vote the best answer to a specific question. Each “author” has a profile with detailed stats for recent posts and answers, activity and “related answers”. Quora has been widely regarded as a revolutionary knowledge platform comparable to Wikipedia.

The iPhone app brings many of the features that made Quora popular on mobile devices (the app also runs on the iPod touch) and adds a “nearby feature” to browse topics on a map, add or answer questions about a place near you, or simply explore questions on a map overlay. You can view your profile, ask and answer questions, or read your feed for interesting questions and topics you might want to follow.

The developers of the Quora app write:

When Neeraj Agrawal and I started working on the app earlier this year, we spent a lot of time thinking about how to translate both the experience and the technology of Quora to a mobile platform. We rethought the design from the ground up and worked hard to make it fast and native while strengthening the core product. Now, just like on the Quora web site, you can read your feed, search and add questions, check your notifications and add answers and posts.

We’ve also made existing features like Shuffle even better. You can find Shuffle at the bottom of your feed. It’s perfect for surfacing even more great content when you’re stuck at a bus stop and looking for something to read.

Quora for iPhone is available for free on the App Store.
