App harnesses crowd-sourcing, a departure from their text-based service.

You may know ChaCha as a text messaging-based search service. ChaCha also answers questions on Twitter, so it is fitting that they’ve launched a Facebook app.

Basically, you ask a question and then you can direct it to specific people in your network, post it to your wall, or open it up to anyone.

This type of Q&A search relies on the power of the crowd. Kind of reminds me of Aardvark, which was acquired by Google last week.

Check out the screenshots below and then check out the ChaCha Facebook app for yourself here.
