Who needs Q&A sites when you have the Google right? Not exactly. There's still some things that real people who are alive and kicking with experiences you might never go through can offer better than Google.
Like if you had a particular question on people's tastes or favorite brunch spot or if tap water is okay to drink in New York City or basically anything you put in Google but have to dig around for too many minutes to find the link you wanted to find. Ask.com just released a new app for Android and it puts your questions in contact with people who want to answer them. So more personal than Google, more useful than Yahoo Answers. [Android Market]
