NEW YORK — Facebook has topped 1 billion users, but the past few months have not been easy.

CEO Mark Zuckerberg updated his Facebook status on Thursday to announce that the social networking site has more than 1 billion active users each month.

“Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life,” he posted.

Zuckerberg also made it clear that he hopes many more will sign up for Facebook. “I am committed to working every day to make Facebook better for you, and hopefully together one day we will be able to connect the rest of the world too.” he said.

The company has had a difficult time lately. There were trading glitches the day it went public in May and concerns since then about its revenue potential. It’s also facing lawsuits from disgruntled shareholders.

Zuckerberg said in a “Today” show interview Thursday that “we’re in a tough cycle now and that doesn’t help morale, but people are focused on what they’re building.”
