Facebook: Reaches 500 Million Members!
Published July 22, 2010 | 
We predicted earlier this year when Facebook turned 6 years old and passed 400 million members at the same time, that 500 million members would be reached before the end of the year. Now, a little more than halfway through 2010, Facebook has announced reaching the 500 million member milestone and launched a new application called Facebook Stories where you can share your story and read hundreds of others.
Congratulations to Facebook on reaching the important 500 million member milestone, which raises the obvious question, “When will Facebook reach 600 million members?
