Things happen quickly in the industry, including changes in employment. Here's a quick and dirty list of the biggest moves that hit our radar over the last couple of weeks:

Klout Nabs Former Yahoo Exec

Social influence measurement provider, Klout (news, site), has a new a VP of Engineering: David Mariani, a seasoned analytics exec from Yahoo

At Yahoo, Mariani managed engineering for all of the company's audience and advertising analytics platforms. Before that, he served at Blue Lithium as CTO, and founded MineShare.

"Dave’s goal at Klout will be to continue building a world class engineering team and culture," wrote Klout CEO Joe Fernandez. "Even though we currently process an amazing amount of data, we are also challenging Dave to add more services for us to analyze and to do this analysis faster and with more granularity, transparency and actionability. This is a huge challenge but we couldn’t imagine a better person for the job!"

Bit.ly Hires New CEO, Peter Stern

Bit.ly's (news, site) John Borthwick has left his throne to new CEO, Peter Stern.

Stern, co-founder of webmail platform Zenbe, chose to stay behind when his company was acquired by Facebook late last year.

Meanwhile, Bitly has done well as a link shortener. The service raised US$ 14 million in just a few years, and reportedly shrinks more than 8 billion Web addresses per month. Moreover, it is beginning to give rise to additional products. For instance, bitly data is at the core of its News.me reader for the iPad.

“You can expect bitly to build on its strengths, enabling people to explore and share content in other ways beyond url shortening," said Stern, who looks to have his work cut out for him as the company's first full-time CEO

Technorati

Technorati (news, site), a company best known for its data collection on social media networks and blogs, has appointed both a new CEO and CTO.

Shani Higgins, former senior vice president and general manager, is now CEO, replacing Richard Jalichandra, who will become executive chairman. Abderrezak Kamel is not the company's CTO.

“From the Richard Jalichandra perspective, the moving to an executive chairman role really allows him to focus on what he loves to do… which is the M&A component and being sort of the outward voice for the company,” explained Higgins. “It’s a natural succession for me to sort of move into more of an exterior [role] as well as continuing to maintain the interior role I’ve been playing," she added.

Going forward, the Technorati team plans to produce products that offer more ROI and engagement for publishers, advertisers, and their audiences.
