Foursquare now has 20 million plus members!

Foursquare has announced that they now have more than 20 million registered users around the world.

The service has also now seen more than 2 billion check-ins.

Foursquare said in a statement:

In 2010, foursquare fans declared April 16 4sqDay (4/4^2 – nerds after our own heart!). Two years and two billion check-ins later, you’re still why we get out of bed each day. Thanks to all 20 million of you for making us part of your lives. Happy 4sqDay!

Foursquare is the only major check-in service provider left in the market. Facebook recently acquired Gowalla and discontinued the service. They have also reduced the focus on location based check-in service on their own platform.

Google Latitude is the only major player trying to expand its presence. Though a lot of Facebook users prefer to check-in using their social networking account.
