TechCrunch: Instagram’s User Count Now At 40 Million, Saw 10 Million New Users In Last 10 Days

Since the launch of its Android app, Instagram’s user base grew from 30 to 40 million. That’s over 1,000,000 new users a day.

Now, I’m sure it’s not all Android users — buzz factor alone will drive new iPhone users to download, too — but compared to the “outcry” of people upset over the Facebook deal, it’s still impressive. Although, it could be a very vocal minority. It’s a crying shame that we’ll probably never see those numbers.
