Facebook-owned photo sharing service Instagram today for the first time revealed some hard numbers on its performance and user base. Instagram has passed 90 million monthly active users, which is a huge number for any casual photo sharing service, no matter how you look at it. The company also confirmed that it is serving 40 million photographs each day, averaging to a little more than two photos per user shared each day. Wondering about how many likes and comments people post each day?

Actually, the right way to ask about this particular metric is: how many likes and comments do users post to Instagram each second?

Answer: 8,500 likes per second and a cool thousand comments per second.

Impressive, no?

Mike Isaac of AllThingsD suspects Instagram’s move is defensive and in response to an outrage following a change in ad terms. Co-founder Kevin Systrom told the Wall Street Journal-owned blog that no, Instagram hasn’t seen any decline in active user, as New York Post asserted last month.

Instagram continues to see very strong growth around the world. With many of the product and internationalization improvements we’ve made, we’ve been excited to see these efforts resonate with users globally.

Instagram quietly revealed stats on its press page, as shown on the screenshot below.

The 90 million active monthly users number is actually up ten percent from December to January, notes AllThingsD.

As for the discrepancy between latest data and the 100 million user milestone reported in September 2012:

You may flinch when you see the new 90 million number compared to the 100 million user milestone the company announced in September of last year. But again, that’s not an apples-to-apples comparison. Since the company’s inception, Instagram has only released its registered user number publicly, while choosing not to disclose active user numbers.
