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.
