Yesterday, Q&A social network Quora revealed that it is seeing more than 100 million monthly unique visitors.

This is an increase of 22 percent from January, when it reported having 80 million.

However, the company declined to comment on where most of the growth is coming from, though the increase could be attributed in part to the release of a number of updates.

The site has seen some renowned individuals participate in conversations on its site, including, Facebook’s Sheryl Sandberg, former Secretary of State and presidential candidate Hillary Clinton, and President Barack Obama.

Adam D’Angelo, the CEO of Quora said that he’s not paying much attention to the number of monthly unique visitors:

“We usually optimize for quality and that comes with a tradeoff against volume.”
