Google has acquired Jaiku, a micro-blogging application for mobile phones that lets users post and browse short messages it calls "jaikus."

The acquisition is one in a series of moves by Google to offer more services through mobile phones.

Jaiku users can also share their activities via the web or instant messaging, according to the company.

Google product manager Tony Hsieh said on Google blog that current Jaiku users can continue to use the service as usual. He said new users will be able to sign up for an invitation when Google is ready to expand the service.

According to Hsieh, Google plans to use the ideas and technology behind Jaiku to make "compelling and useful products," adding that the company doesn't have any specific plans to announce right now.

"We're excited about helping drive the next round of developments in web and mobile technology," Hsieh wrote in the blog. "We... are looking forward to working [with Jaiku] on new and innovative ways of keeping people connected."
