Lawyers and other professionals are using Quora to build their reputation and build their bonafides.

In the past, there hasn't been much reliable information about startups and small businesses available online. It's information that's really valuable, and it's information that people want to share.

You can go to Pinterest, and they'll get to know who your friends are, but they don't get to know very much about what you've done in the past. They're starting with little information about you, and they have to do this personalization.

I read a lot of science fiction, but I also mixed it up with a lot of other genres: crime, literary fiction, as well as nonfiction. Author-wise, I'm a fan of Stephen King, Lauren Beukes, Robert McCammon, Raymond Chandler, Greg Rucka, Ed Brubaker and Gail Simone, among many others.
