Reddit has seen its user population skyrocket, but that growth is forcing it to spend money to keep up with the flow.

The company revealed its latest traffic stats in a blog posted yesterday.

Last month, Reddit recorded more than 3.8 billion page views and more than 46 million unique visitors. Those page views alone are double what the Web site saw a year ago, according to VentureBeat.

The huge increase in traffic means Reddit has had to add more servers and other equipment and bring in more staff to maintain its site. That raises the question of how to pay for all those upgrades and new hires.
