.... It's reported that Twitter's now up to 175 million users, which is itself 30 million users greater than the numbers that Williams was reporting in September—145 million. If you do the math, that's a growth rate of roughly 15 million users per month, or about half a million users per day. Back in April of this month, Twitter co-founder Biz Stone said that Twitter only had a 300,000-per-day user growth rate. As well, Stone was reporting back then that Twitter had around 105 million users. We won't crunch the numbers again, but it's clear to see that Twitter's been undergoing some phenomenal growth rates lately. That's especially if you compare today's numbers to the kinds of figures that the company was touting last year—58 million users in 2009—or the meager 503,000 users that Twitter enjoyed three years ago.
So what does this mean, long-term? If its current growth rate continues, Twitter's sure to hit 200 million users before the year's end.
There's been no update as to how Twitter's users access the service or where they come from, however. In April, Stone was running with the figure that 75 percent of all Twitter's traffic comes from outside the site—external, third-party applications that tap into Twitter's service in various fashions. New updates like a redesign of Twitter.com and the addition of new interactive features alongside popular, real-world events likely account for a bit of Twitter's overall growth, but there's been no indication of just how much Twitter's lifeblood of third-party apps have contributed to the surge.
