Twitter Update from Chirp

Twitter held their annual developer conference called Chirp on April 14-15th, and it gathered quite a crowd. I recently came across a great summary of Twitter’s latest stats, collected and published by Ben Lorica, a Senior Analyst in the Research Group at O’Reilly Media. Thanks Ben!

Here are some of the key take-aways:

1. Number of registered users: 105,779,710 (1,500% growth over the last three years.)

2. Number of new sign-ups per day: ~ 300,000 (More recently, 60% of new accounts were from outside the U.S.)

3. Number of new tweets per day: 55 million

4. Number of unique daily visitors to the site ~ 180 million. (That’s actually dwarfed by the traffic that flows through twitter’s API — 75% of traffic is through the API.)

5. Number of API requests per day: 3 billion

6. Number of registered apps: 100,000 (from 50,000 in Dec/2009)

7. Number of search queries per day: 600 milion

8. Twitter’s instance, of their recently open-sourced graph database (FlockDB), has 13 billion edges and handles 100,000 reads per second.

9. Number of servers: “… in the hundreds”

10. BlackBerry’s just released twitter app accounted for 7% of new sign-ups over the last few days

11. A NY Times story gets tweeted every 4 seconds.
