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.
