FACT CHECK: 500 million users is over 25% of the world's online population.

Actually, the last time I checked http://www.census.gov/main/www/popclock.html shows the world population at 6.8billion. So 500 million would only be 7% of the worlds population. Impressive, but nowhere near 25%.

Not everybody in the world is online, and thus not part of the worlds online population.

Don't forget the word "online" in the original statement.
