Twitter Employees Increased by 30% in 2010

Dick Costolo revealed some pretty interesting facts about Twitter at CES on Friday during his sit-down session with All Things D’s Kara Swisher. The company saw a nearly 30% increase in its employee count in 2010, and has big plans for mobile. Find out what else Costolo revealed below.

Sitting on stage at CES, Costolo spoke about Twitter’s future, its stance on offering an IPO, and the importance it places on mobile, among other things.

To start the ball rolling, Swisher got Costolo talking about the lighter side of Twitter: its integration with TV, celebrity culture and its mobile offerings.

Costolo noted that shows like Glee send TV viewers to Twitter in droves while the show is on, but when it ends, so does the Twitter chatter. He mentioned that the company is still figuring out whether pushing Twitter integration with TVs is a smart move. Costolo also discussed how celebrities flocked to Twitter in recent months, noting that the majority of the top 200 or 300 tweeters are actors, musicians or other types of celebrities.

Moving on to mobile, Costolo revealed that 40% of all tweets come from a mobile device, up from 25% a year ago. This number could have serious implications for how Twitter approaches its integration with mobile devices.

Costolo also mentioned that Twitter hired 100 employees in the last quarter of 2010, of about 350 total. This is massive growth, and suggests they’re gearing up for some big moves in 2011.

On the business side of things, Swisher asked Costolo about any possible plans that Twitter might sell – which Costolo quashed, saying that they want to continue to remain as a standalone company as they’ve only accomplished 1% of what they have planned.
