About one year ago Twitter reached a huge milestone: one billion tweets. Four months ago, 5 billion tweets were served. And now, in about one day, Twitter should reach another very important milestone: 10 billion tweets.

Notice the trend? Although Twitter has been somewhat struggling with traffic (compared to its earlier immense growth) in the last couple of months, it still managed to go from five to ten billion tweets in four months; quite a remarkable achievement.

Counting tweets is actually quite easy: just look at the URL of any tweet. The number at the end of the URL seems to be the number of that tweet, and at this moment the number of one of the latest tweets is 9917803012. If this seems like a long way to go before we reach one billion, check out this counter. Yup, we’re getting there fast.

The five billionth (now deleted) tweet was a simple “Oh lord,” written by Robin Sloan. I wonder what the ten billionth tweet will say?
