Twitter have some choice words for Instagram, and its not in congratulations.

Instagram made headlines yesterday for reaching its major milestone of 300 million active monthly users, officially having more monthly active users than Twitter. The popular photo and video sharing app also announced it would be copying Twitter to include verified accounts to eliminate fake profiles and reduce spam.

So what does Twitter think about all this? According to Twitter co-founder Evan Williams, he couldn't care less. In fact, he doesn't "give a sh*t" if Instagram now has more users, also adding that he cares more about "breadth versus depth."

With Twitter's 284 million users, Twitter's co-founder said that user count is the wrong metric to focus on. Instagram was sold to Facebook in 2012 for $1 billion. In comparison, Twitter is a $24 billion publicly traded company.

"If you think about the impact Twitter has on the world versus Instagram, it's pretty significant. It's at least apples to oranges," Williams said.

"Twitter is what we wanted it to be," he added. "It's this real-time information network where everything in the world that happens on Twitter - important stuff breaks on Twitter and world leaders have conversations on Twitter. If that's happening, I frankly don't give a sh*t if Instagram has more people looking at pretty pictures." 

Williams credited Facebook for doing a good job establishing a Wall Street metric. And when it comes down to it, he said Twitter's monetization has been going well thus far.

"Twitter makes a hell of a lot more money than Instagram, if that's what Wall Street cares about," he said.
