Twitter By The Numbers

I collected some interesting stats from today’s presentations at Chirp. Over a thousand people attended the conference and the numbers below attest to how vibrant the Twitter platform is. Today’s announced API enhancements (e.g., user streams, annotations) will make the Twitter ecosystem even more interesting:

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

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

3. # of new tweets per day: 55 million

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

5. # of API requests per day: 3 billion

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

7. # of search queries per day: 600 milion

8. Twitter’s instance, of their recently open-sourced graph database (FlockDB), has 300 13 billion edges and handles 100,000 reads per second.

9. # of servers1: “… 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.

(1) No surprise that Google has the most servers.
